We can Break Chip PIC12HV609 Binary, please view the Chip PIC12HV609 features for your reference:

The PIC12F609/615/617/12HV609/615 has a 13-bit program counter capable of addressing an 8K x 14 program memory space. Only the first 1K x 14 (0000h-03FFh) for the PIC12F609/615/12HV609/615 is physically implemented. For the PIC12F617, the first 2K x 14 (0000h-07FFh) is physically implemented.

Accessing a location above these boundaries will cause a wrap-around within the first 1K x 14 space for PIC12F609/615/12HV609/615 devices, and within the first 2K x 14 space for the PIC12F617 device. The Reset vector is at 0000h and the interrupt vector is at 0004h (see Figure 2-1). The data memory (see Figure 2-3) is partitioned into two banks, which contain the General Purpose Registers (GPR) and the Special Function Registers (SFR).

Special Function Registers are located in the first 32 locations of each bank. Register locations 40h-7Fh in Bank 0 are General Purpose Registers, implemented as static RAM. For the PIC12F617, the register locations 20h-7Fh in Bank 0 and

A0h-EFh in Bank 1 are general purpose registers implemented as Static RAM. Register locations F0h-FFh in Bank 1 point to addresses 70h-7Fh if Break Chip

On-chip Program Memory in Bank 0. All other RAM is unimplemented and returns ‘0’ when read. The RP0 bit of the STATUS register is the bank select bit. The register file is organized as 64 x 8 in the PIC12F609/615/12HV609/615, and as 128 x 8 in the PIC12F617. Each register is accessed, either directly or indirectly, through the File Select Register (FSR) (see Section 2.4 “Indirect Addressing, INDF and FSR Registers”).

The Special Function Registers are registers used by the CPU and peripheral functions for controlling the desired operation of the device (see Table 2-1). These registers are static RAM. The special registers can be classified into two sets: core and peripheral. The Special Function Registers associated with the “core” are described in this section when Break IC.

Those related to the operation of the peripheral features are described in the section of that peripheral feature. The STATUS register, shown in Register 2-1, contains:

· the arithmetic status of the ALU

· the Reset status

· the bank select bits for data memory (RAM)

The STATUS register can be the destination for any instruction, like any other register. If the STATUS register is the destination for an instruction that affects the Z, DC or C bits, then the write to these three bits is disabled. These bits are set or cleared according to the device logic.

Furthermore, the TO and PD bits are not writable. Therefore, the result of an instruction with the STATUS register as destination may be different than intended.

For example, CLRF STATUS, will clear the upper three bits and set the Z bit. This leaves the STATUS register as ‘000u u1uu’ (where u = unchanged).

As for MCU break  (microcontroller unit), hardware security in microcontrollers is being constantly improved. Because the tools for mcu break are becoming more sophisticated, better and better security protection is required. Rapid co-evolution is driven by this continuous battle between chip manufacturers and chip attackers.

Another threat that must be considered is that a great deal of second-hand semiconductor manufacturing and testing equipment appears on the market. It cannot be used to break high-end MCUs, but should be enough to break MCU chips manufactured with older technology. For example, while 90 nm manufacturing technology is currently leading-edge, most MCUs are produced with 0.35 µm technology and smartcards with 0.25 µm technology.

The simplest mode of operation is the Normal mode (WGMn3:0 = 0). In this mode the counting direction is always up (incrementing), and no counter clear is performed.

The counter simply overruns when it passes its maximum 16-bit value (MAX = 0xFFFF) and then restarts from the BOTTOM (0x0000).

In normal operation the Timer/Counter Over-flow Flag (TOVn) will be set in the same timer clock cycle as the TCNTn becomes zero.

The TOVn Flag in this case behaves like a 17th bit, except that it is only set, not cleared. However, combined with the timer overflow interrupt that automatically clears the TOVn Flag, the timer resolution can be increased by software.

There are no special cases to consider in the Normal mode, a new counter value can be written anytime. The Input Capture unit is easy to use in Normal mode. However, observe that the maximum interval between the external events must not exceed the resolution of the counter.

If the interval between events are too long, the timer overflow interrupt or the prescaler must be used to extend the resolution for the capture unit. The Output Compare units can be used to generate interrupts at some given time.

Using the Output Compare to generate waveforms in Normal mode is not recommended, since this will occupy too much of the CPU time. In Clear Timer on Compare or CTC mode (WGMn3:0 = 4 or 12), the OCRnA or ICRn Register are used to manipulate the counter resolution.

In CTC mode the counter is cleared to zero when the counter value (TCNTn) matches either the OCRnA (WGMn3:0 = 4) or the ICRn (WGMn3:0 = 12). The OCRnA or ICRn define the top value for the counter, hence also its resolution.

This mode allows greater control of the compare match output frequency. It also simplifies the operation of counting external events. The timing diagram for the CTC mode is shown in Figure 54. The counter value (TCNTn) increases until a compare match occurs with either OCRnA or ICRn, and then counter (TCNTn) is cleared.

An interrupt can be generated at each time the counter value reaches the TOP value by either using the OCFnA or ICFn Flag according to the register used to define the TOP value. If the interrupt is enabled, the interrupt handler routine can be used for updating the TOP value. However, changing the TOP to a value close to BOTTOM when the counter is running with none or a low prescaler value must be done with care since the CTC mode does not have the double buffering feature.

If the new value written to OCRnA or ICRn is lower than the current value of TCNTn, the counter will miss the compare match. The counter will then have to count to its maximum value (0xFFFF) and wrap around starting at 0x0000 before the compare match can occur. In many cases this feature is not desirable. An alternative will then be to use the fast PWM mode using OCRnA for defining TOP (WGMn3:0 = 15) since the OCRnA then will be double buffered.

For generating a waveform output in CTC mode, the OCnA output can be set to toggle its logical level on each compare match by setting the Compare Output mode bits to toggle mode (COMnA1:0 = 1). The OCnA value will not be visible on the port pin unless the data direction for the pin is set to output (DDR_OCnA = 1).

The waveform generated will have a maximum frequency of fOCnA = fclk_I/O/2 when OCRnA is set to zero (0x0000). The waveform frequency is defined by the following equation.
