bit 0
bit 7
bit 7
bit 6
Unimplemented: Read as ‘0’
TMR1GE: Timer± Gate Enable bit
If TMR±ON = 0:
This bit is ignored
If TMR±ON = ±:
1= Timer± is on if T±G pin is low
0= Timer± is on
bit 5-4
T1CKPS1:T1CKPS0: Timer± Input Clock Prescale Select bits
11= ±:8 Prescale Value
10= ±:4 Prescale Value
01= ±:2 Prescale Value
00= ±:± Prescale Value
bit 3
T1OSCEN: LP Oscillator Enable Control bit
If INTOSC without CLKOUT oscillator is active:
1= LP oscillator is enabled for Timer± clock
0= LP oscillator is off
Else:
This bit is ignored
bit 2
T1SYNC: Timer± External Clock Input Synchronization Control bit
TMR±CS = ±:
1= Do not synchronize external clock input
0= Synchronize external clock input
TMR±CS = 0:
This bit is ignored. Timer± uses the internal clock.
bit ±
bit 0
TMR1CS: Timer± Clock Source Select bit
1= External clock from T±OSO/T±CKI pin (on the rising edge)
0= Internal clock (FOSC/4)
TMR1ON: Timer± On bit
1= Enables Timer±
0= Stops Timer±
Legend:
R = Readable bit
W = Writable bit
’±’ = Bit is set
U = Unimplemented bit, read as ‘0’
’0’ = Bit is cleared x = Bit is unknown
- n = Value at POR
