1: Other (non power-up) resets include MCLR Reset and Watchdog Timer Reset during normal operation.
2: The IRP and RP1 bits are reserved, always maintain these bits clear.
3: The PORTD, PORTE, TRISD, and TRISE registers are not implemented on the PIC16C641/642.
4: Bits PSPIE and PSPIF are reserved on the PIC16C641/642, always maintain these bits clear.
