0x00 10 LATCHED_FAULT_STATUS Latched Fault bit; resets with 1 written to this bit (Read/Write) 0x00 9 SYNC Sync (new data) bit; resets when this register is read (Read only) 0x00

Random read is a mode in which a selected memory address is specified and its data is read. The address is specified by a dummy write input. First, when the EEPROM receives the

The Special Function Registers include the TMR0 register, the Program Counter (PC), the STATUS regis- ter, the I/O registers (ports) and the File Select Register (FSR).. In

To read a program memory location, the user must write two bytes of the address to the EEADR and EEADRH registers, set the EEPGD control bit (EECON1<7>) and then set control

3: This buffer is a Schmitt Trigger input when configured as general purpose I/O and a TTL input when used in the Parallel Slave Port mode (for interfacing to a microprocessor

The OPTION register is a readable and writable register which contains various control bits to configure the TMR0/WDT prescaler, the external RB0/INT interrupt, TMR0, and the

The Special Function Registers include the TMR0 register, the Program Counter Low PCL, the STATUS register, the I/O register port and the File Select Register FSR.. In addition,
