Details on
page:
Legend: x = unknown, u = unchanged, – = unimplemented, q = value depends on condition
Note 1: RA6 and associated bits are configured as port pins in RCIO, ECIO and INTIO2 (with port function on RA6) Oscillator mode only and read ‘0’
in all other oscillator modes.
2: RA7 and associated bits are configured as port pins in INTIO2 Oscillator mode only and read ‘0’ in all other modes.
3: Bit 21 of the PC is only available in Test mode and Serial Programming modes.
4: The RA5 port bit is only available when MCLRE fuse (CONFIG3H<7>) is programmed to ‘0’. Otherwise, RA5 reads ‘0’. This bit is read-only.
