Replicate PIC12F519 Microprocessor Flash Program

Replicate PIC12F519 Microprocessor Flash Program can help engineer to unlock ic chip secured pic12f519 binary from its flash memory, to readout microchip locked pic12f519 source code;

The LVD module has an additional feature that allows the user to supply the trip voltage to the module from an external source. This mode is enabled when bits, LVDL3:LVDL0, are set to ‘1111’. In this state, the com- parator input is multiplexed from the external input pin when breaking microcontroller pic12f629 flash, LVDIN (Figure 18-3). This gives users flexibility, because it allows them to configure the Low-Voltage Detect interrupt to occur at any voltage in the valid operating range.

bit 7-6                Unimplemented: Read as ‘0’

bit 5                    IRVST: Internal Reference Voltage Stable Flag bit

1 = Indicates that the Low-Voltage Detect logic will generate the interrupt flag at the specified voltage range

0 = Indicates that the Low-Voltage Detect logic will not generate the interrupt flag at the specified volt- age range and the LVD interrupt should not be enabled by breaking dspic30f4011 mcu flash memory;

bit 4                    LVDEN: Low-Voltage Detect Power Enable bit

1 = Enables LVD, powers up LVD circuit

0 = Disables LVD, powers down LVD circuit

bit 3-0                LVDL<3:0>: Low-Voltage Detection Limit bits(1)

1111 = External analog input is used (input comes from the LVDIN pin)

1110 = 4.04V-5.15V

1101 = 3.76V-4.79V

1100 = 3.58V-4.56V

1011 = 3.41V-4.34V

1010 = 3.23V-4.11V

1001 = 3.14V-4.00V

1000 = 2.96V-3.77V

0111 = 2.70V-3.43V

0110 = 2.53V-3.21V

0101 = 2.43V-3.10V

0100 = 2.25V-2.86V

0011 = 2.16V-2.75V

0010 = 1.99V-2.53V

0001 = Reserved

0000 = Reserved

Note 1:    LVDL<3:0> modes, which result in a trip point below the valid operating voltage of the device, are not tested.
