Unimplemented: Read as ‘0’
EXCLKMX: TMR0/T5CKI External Clock MUX bit⁽¹⁾
1 = TMR0/T5CKI external clock input is multiplexed with RC3
0 = TMR0/T5CKI external clock input is multiplexed with RD0
PWM4MX: PWM4 MUX bit⁽¹⁾
1 = PWM4 output is multiplexed with RB5
0 = PWM4 output is multiplexed with RD5
SSPMX: SSP I/O MUX bit⁽¹⁾
1 = SCK/SCL clocks and SDA/SDI data are multiplexed with RC5 and RC4, respectively. SDO output
is multiplexed with RC7.
0 = SCK/SCL clocks and SDA/SDI data are multiplexed with RD3 and RD2, respectively. SDO output
is multiplexed with RD1.
Unimplemented: Read as ‘0’
FLTAMX: FLTA MUX bit⁽¹⁾
1 = FLTA input is multiplexed with RC1
0 = FLTA input is multiplexed with RD4
Note 1: Unimplemented in PIC18F2331/2431 devices; maintain this bit set.
