Unlock PIC16F1708 microprocessor protected firmware and copy embedded source code from encrypted PIC16F1708 microcontroller flash program memory in the format of binary file and decrypt locked MCU PIC16F1708 eeprom data memory in the format of heximal software;
The EUSART transmitter block diagram is shown in below Figure. The heart of the transmitter is the serial Transmit Shift Register (TSR), which is not directly accessible by software. The TSR obtains its data from the transmit buffer, which is the TXREG register and we can use it to Unlock PIC16F1708 Microprocessor Protected Firmware.
A transmission is initiated by writing a character to the TXREG register. If this is the first character, or the previous character has been completely flushed from the TSR for the completion of Read Out Content From Protected MCU PIC18F4431, the data in the TXREG is immediately transferred to the TSR register.
If the TSR still contains all or part of a previous character, the new character data is held in the TXREG until the Stop bit of the previous character has been transmitted. The pending character in the TXREG is then transferred to the TSR in one TCY immediately following the Stop bit transmission to facilitate the process of Copy Content From Encrypted PIC18F4423 Flash Area.
The transmission of the Start bit, data bits and Stop bit sequence commences immediately following the transfer of the data to the TSR from the TXREG after Unlock Microcontroller.
