CMCON1 – COMPARATOR CONTROL 1 REGISTER (ADDRESS: 1Ah)
Unimplemented: Read as ‘0’
T1GSS: Timer1 Gate Source Select bit
1 = Timer1 gate source is T1G pin (RA4 must be configured as digital input)
0 = Timer1 gate source is Comparator 2 output
C2SYNC: Comparator 2 Synchronize bit
1 = C2 output synchronized with falling edge of Timer1 clock
0 = C2 output not synchronized with Timer1 clock
