TIMER1 MODULE
The Timer1 timer/counter module incorporates these
features:
Software selectable operation as a 16-bit timer or
counter
Readable and writable 8-bit registers (TMR1H
and TMR1L)
Selectable clock source (internal or external) with
device clock or Timer1 oscillator internal options
Interrupt-on-overflow
Reset on ECCP Special Event Trigger
Device clock status flag (T1RUN)
Timer with gated control
Figure 13-1 displays a simplified block diagram of the
Timer1 module.
The module incorporates its own low-power oscillator
to provide an additional clocking option. The Timer1
oscillator can also be used as a low-power clock source
for the microcontroller in power-managed operation.
Timer1 is controlled through the T1CON Control
register (Register 13-1). It also contains the Timer1
oscillator Enable bit (T1OSCEN). Timer1 can be
enabled or disabled by setting or clearing control bit,
TMR1ON (T1CON<0>).
The FOSC clock source (TMR1CS<1:0> = 01) should
not be used with the ECCP capture/compare features.
If the timer will be used with the capture or compare
features, always select one of the other timer clocking
options.

bit 7
bit 0
Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7-6
TMR1CS<1:0>:
Timer1 Clock Source Select bits
10
= Timer1 clock source is T1OSC or T1CKI pin
01
= Timer1 clock source is system clock (FOSC)(1)
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:
Timer1 Crystal Oscillator Enable bit
1
= Timer1 oscillator circuit enabled
0
= Timer1 oscillator circuit disabled
The oscillator inverter and feedback resistor are turned off to eliminate power drain.
bit 2
T1SYNC:
Timer1 External Clock Input Synchronization Select bit
TMR1CS<1:0> = 10:
1
= Do not synchronize external clock input
0
= Synchronize external clock input
TMR1CS<1:0> = 0x:
This bit is ignored. Timer1 uses the internal clock when TMR1CS<1:0> = 0x.
bit 1
RD16:
16-Bit Read/Write Mode Enable bit
1
= Enables register read/write of Timer1 in one 16-bit operation
0
= Enables register read/write of Timer1 in two 8-bit operations
bit 0
TMR1ON:
Timer1 On bit
1
= Enables Timer1
0
=Stops Timer1
Note 1:
The FOSC clock source should not be selected if the timer will be used with the ECCP capture/compare
features.
