Legend:
Note 1:
2:
– = Unimplemented locations read as ‘0’, u= unchanged, x= unknown, q= value depends on condition, shaded = unimplemented
IRP and RP1 bits are reserved, always maintain these bits clear.
GP3 pull-up is enabled when MCLRE is ‘1’ in the Configuration Word register.
3:
MCLR and WDT Reset does not affect the previous value data latch. The GPIF bit will clear upon Reset but will set again if the mismatch
exists.
4:
TRISIO3 always reads as ‘1’ since it is an input only pin.
