Read Microchip IC PIC18LF248 Program and data from its memory after crack MCU tamper resistance system by get access to the internal circuitry pattern and locate the security fuse bit.
The Serial Peripheral Interface (SPI) allows high-speed full-duplex, synchronous data transfer between different devices. Devices can communicate using a master-slave scheme, and data is transferred both to and from the devices simultaneously when read out mcu pic16lf876 heximal.
PORTC, PORTD, PORTE, and PORTF each has one SPI. Notation of these peripherals are SPIC, SPID, SPIE, and SPIF, respectively.

The Universal Synchronous and Asynchronous serial Receiver and Transmitter (USART) is a highly flexible serial communication module. The USART supports full duplex communication, and both asynchronous and clocked synchronous operation. The USART can also be set in Master SPI mode to be used for SPI communication.
Communication is frame based, and the frame format can be customized to support a wide range of standards. The USART is buffered in both direction, enabling continued data transmission without any delay between frames. There are separate interrupt vectors for receive and transmit complete, enabling fully interrupt driven communication.
Frame error and buffer overflow are detected in hardware and indicated with separate status flags. Even or odd parity generation and parity check can also be enabled. One USART can use the IRCOM module to support IrDA 1.4 physical compliant pulse modulation and demodulation for baud rates up to 115.2 kbps.
PORTC, PORTD, PORTE, and PORTF each has two USARTs. Notation of these peripherals are USARTC0, USARTC1, USARTD0, USARTD1, USARTE0, USARTE1, USARTF0, USARTF1, respectively.
