bit 7 bit 0
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
For 8-Pin Devices (
PIC12(L)F1822):
0 = RX/DT function is on RA1
1 = RX/DT function is on RA5
For 14-Pin Devices (
PIC16(L)F1823):
0 = RX/DT function is on RC5
1 = RX/DT function is on RA1
bit 6 SDOSEL: Pin Selection bit
For 8-Pin Devices (
PIC12(L)F1822):
0 = SDO function is on RA0
1 = SDO function is on RA4
For 14-Pin Devices (
PIC16(L)F1823):
0 = SDO function is on RC2
1 = SDO function is on RA4
bit 5 SSSEL: Pin Selection bit
For 8-Pin Devices (
PIC12(L)F1822):
0 =SS
function is on RA3
1 =SS
function is on RA0
For 14-Pin Devices (
PIC16(L)F1823):
0 =SS
function is on RC3
1 =SS
function is on RA3
bit 4 Unimplemented: Read as ‘0’
bit 3 T1GSEL: Pin Selection bit
0 = T1G function is on RA4
1 = T1G function is on RA3
bit 2 TXCKSEL: Pin Selection bit
For 8-Pin Devices (
PIC12(L)F1822):
0 = TX/CK function is on RA0
1 = TX/CK function is on RA4
For 14-Pin Devices (
PIC16(L)F1823):
0 = TX/CK function is on RC4
1 = TX/CK function is on RA0
bit 1 P1BSEL: Pin Selection bit
(1)
For 8-Pin Devices (PIC12(L)F1822):
0 = P1B function is on RA0
1 = P1B function is on RA4
For 14-Pin Devices (
PIC16(L)F1823):
P1B function is always on RC4
bit 0 CCP1SEL: Pin Selection bit
(1)
For 8-Pin Devices (PIC12(L)F1822):
0 = CCP1/P1A function is on RA2
1 = CCP1/P1A function is on RA5
For 14-Pin Devices (
PIC16(L)F1823):
CCP1/P1A function is always on RC5
