Copy Microcontroller PIC16C58B Program out from memory include the flash and eeprom, the heximal extracted can be reprogrammed to other blank MCU which will provide the same functions as original version after MCU cracking;
PIC16C58B devices have a 12-bit wide L.I.F.O. hardware push/pop stack.
A CALL instruction will push the current value of stack 1 into stack 2 and then push the current program counter value, incremented by one, into stack level 1.
If more than two sequential CALL’s are executed, only the most recent two return addresses are stored. ARETLW instruction will pop the contents of stack level 1 into the program counter and then copy stack level 2 contents into level 1 to conquer invasive mcu extraction.
If more than two sequential RETLW’s are executed, the stack will be filled with the address previously stored in level 2. Note that the W register will be loaded with the literal value specified in the instruction.
This is particularly useful for the implementation of data look-up tables within the program memory. Upon any reset, the contents of the stack remain unchanged, however the program counter (PCL) will also be reset to 0.
The INDF register is not a physical register. Addressing INDF actually addresses the register As with any other register, the I/O register can be written and read under program control when read mcu at89c51cc03 flash.
However, read instructions (e.g., MOVF GPIO,W) always read the I/O pins independent of the pin’s input/output modes. On RESET, all I/O ports are defined as input (inputs are at hi-impedance) since the I/O control registers are all set.
See Section 7.0 for SCL and SDA description for PIC16C58B. GPIO is an 8-bit I/O register. Only the low order 6 bits are used (GP5:GP0). Bits 7 and 6 are unimplemented and read as ‘0’s before read Microcontroller at89c51cc01 flash.
Please note that GP3 is an input only pin. The configuration word can set several I/O’s to alternate functions. When acting as alternate functions the pins will read as ‘0’ during port read.
Pins GP0, GP1, and GP3 can be configured with weak pull-ups and also with wake-up on change. The wake-up on change and weak pull-up functions are not pin selectable. If pin 4 is configured as MCLR, weak pull-up is always on and wake-up on change for this pin is not enabled.
