– = Unimplemented locations read as ‘0’, u = unchanged, x = unknown, q = value depends on condition shaded = unimplemented
Other (non Power-up) Resets include MCLR Reset, Brown-out Detect and Watchdog Timer Reset during normal operation.
IRP and RP1 bits are reserved, always maintain these bits clear.
PIC16F676 only.
