Legend:
R = Readable bit
-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared x = Bit is unknown
bit 7-6
bit 5-4
Unimplemented: Read as ‘0’
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
bit 3
bit 2
T1OSCEN: Timer1 Oscillator Enable Control bit
1= Timer1 oscillator is enabled
0= Timer1 oscillator is disabled
T1SYNC: Timer1 External Clock Input Synchronization Control bit
TMR1CS = 1:
1= Do not synchronize external clock input
0= Synchronize external clock input
TMR1CS = 0:
This bit is ignored. Timer1 uses the internal clock
bit 1
bit 0
TMR1CS: Timer1 Clock Source Select bit
1= External clock from T1CKI pin (on the rising edge)
0= Internal clock (FOSC/4)
TMR1ON: Timer1 On bit
1= Enables Timer1
0= Stops Timer1
