TMR1CS<1:0>: Timer1 Clock Source Select bits
11 = Timer1 clock source is Capacitive Sensing Oscillator (CAPOSC)
10 = Timer1 clock source is pin or oscillator:
If T1OSCEN = 0:
External clock from T1CKI pin (on the rising edge)
If T1OSCEN = 1:
Crystal oscillator on T1OSI/T1OSO pins
01 = Timer1 clock source is system clock (FOSC)
00 = Timer1 clock source is instruction clock (FOSC/4)
T1CKPS<1:0>: Timer1 Input Clock Prescale Select bits
11 = 1:8 Prescale value
10 = 1:4 Prescale value
01 = 1:2 Prescale value
00 = 1:1 Prescale value
T1OSCEN: LP Oscillator Enable Control bit
1 = Dedicated Timer1 oscillator circuit enabled
0 = Dedicated Timer1 oscillator circuit disabled
T1SYNC: Timer1 Synchronization Control bit
1 = Do not synchronize asynchronous clock input
0 = Synchronize asynchronous clock input with system clock (FOSC)
Unimplemented: Read as ‘0’
TMR1ON: Timer1 On bit
1 = Enables Timer1
0 = Stops Timer1 and clears Timer1 gate flip-flop
