Legend:
Note 1:
x = unknown, u = unchanged, - = unimplemented, read as ‘0’. Shaded cells are not used by the SSP in
SPI mode.
RA7 and associated bits are configured as port pins in INTIO2 Oscillator mode only and read ‘0’ in all other
modes.
2: 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.
