3: Other (non power-up) resets include external reset through MCLR and the Watchdog Timer reset.
4: The BOR bit is reserved on the PIC16C62, always maintain this bit set.
5: The IRP and RP1 bits are reserved on the PIC16C62/62A/R62, always maintain these bits clear.
6: PIE1<7:6> and PIR1<7:6> are reserved on the PIC16C62/62A/R62, always maintain these bits clear.
