21.11 Timer1 Control Register
The Timer1 Control register (T1CON), shown in
Register 21-1, is used to control Timer1 and select the
various features of the Timer1 module.
REGISTER 21-1:
T1CON: TIMER1 CONTROL REGISTER
R/W-0/u
U-0
R/W-0/u
TMR1CS<1:0>
T1CKPS<1:0>
T1OSCEN
T1SYNC
—TMR1ON
bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
u = Bit is unchanged
x = Bit is unknown
-n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set
‘0’ = Bit is cleared
bit 7-6
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)
bit 5-4
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
bit 3
T1OSCEN:
LP Oscillator Enable Control bit
1
= Dedicated Timer1 oscillator circuit enabled
0
= Dedicated Timer1 oscillator circuit disabled
bit 2
T1SYNC:
Timer1 External Clock Input Synchronization Control bit
TMR1CS<1:0> = 1X
1
= Do not synchronize external clock input
0
= Synchronize external clock input with system clock (FOSC)
TMR1CS<1:0> = 0X
This bit is ignored.
bit 1
Unimplemented:
Read as ‘0’
bit 0
TMR1ON:
Timer1 On bit
1
= Enables Timer1
0
= Stops Timer1
Clears Timer1 Gate flip-flop
