Copy Protected Chip PIC16C56 Code
Copy Protected Chip PIC16C56 Code include program of flash and data of eeprom memory, the embedded source code of microcontroller pic16c56 will be replicated after readout frm mcu pic16c56 memory;
The PIC12C5XX device contains an 8-bit ALU and working register. The ALU is a general purpose arithmetic unit. It performs arithmetic and Boolean functions between data in the working register and any register file when attack mcu attiny2313 memory for its firmware.
The ALU is 8-bits wide and capable of addition, subtraction, shift and logical operations. Unless otherwise mentioned, arithmetic operations are two’s complement in nature.
In two-operand instructions, typically one operand is the W (working) register. The other operand is either a file register or an immediate constant before Copy avr mcu atmega165a memory.
In single operand instructions, the operand is either the W register or a file register. The W register is an 8-bit working register used for ALU operations.
It is not an addressable register. Depending on the instruction executed, the ALU may affect the values of the Carry (C), Digit Carry (DC), and Zero (Z) bits in the STATUS register.
The C and DC bits operate as a borrow and digit borrow out bit, respectively, in subtraction. See theSUBWF andADDWF instructions for examples if copy mcu atmega162 flash memory.
A simplified block diagram is shown in Figure 3-1, with the corresponding device pins described in Table 3-1. The PIC12C5XX can directly or indirectly address its register files and data memory.
All special function registers including the code counter are mapped in the data memory. The PIC12C5XX has a highly orthogonal (symmetrical) instruction set that makes it possible to carry out any operation on any register using any addressing mode. This symmetrical nature and lack of ‘special optimal situations’ make codeming with the PIC12C5XX simple yet efficient. In addition, the learning curve is reduced significantly.
