– = Unimplemented locations read as ‘0’, u = unchanged, x = unknown, q = value depends on condition, shaded = unimplemented

MCLR and WDT Reset does not affect the previous value data latch. The RABIF bit will be cleared upon Reset but will set again if the

mismatch exists.

PIC16F685/PIC16F689/PIC16F690 only.

PIC16F677/PIC16F685/PIC16F687/PIC16F689/PIC16F690 only.

Port pins with analog functions controlled by the ANSEL and ANSELH registers will read ‘0’ immediately after a Reset even though the

data latches are either undefined (POR) or unchanged (other Resets).
