Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7
RXDTSEL: Pin Selection bit
1 = RX/DT function is on RA5
0 = RX/DT function is on RA1
bit 6
SDOSEL: Pin Selection bit
1 = SDO function is on RA4
0 = SDO function is on RA0
bit 5
SSSEL: Pin Selection bit
1 =SS function is on RA0
0 =SS function is on RA3
bit 4
Unimplemented: Read as ‘0’
bit 3
T1GSEL: Pin Selection bit
1 = T1G function is on RA3
0 = T1G function is on RA4
bit 2
TXCKSEL: Pin Selection bit
1 = TX/CK function is on RA4
0 = TX/CK function is on RA0
bit 1
P1BSEL: Pin Selection bit
1 = P1B function is on RA4
0 = P1B function is on RA0
bit 0
CCP1SEL: Pin Selection bit
1 = CCP1/P1A function is on RA5
