FIGURE 8-1:
8.1
The 16-bit timer can be placed in the Gated Time Accu-
mulation mode. This mode allows the internal T
increment the respective timer when the gate input sig-
nal (T1CK pin) is asserted high. Control bit TGATE
(T1CON<6>) must be set to enable this mode. The
timer must be enabled (TON = 1) and the timer clock
source set to internal (TCS = 0).
When the CPU goes into the Idle mode, the timer will
stop incrementing, unless TSIDL = 0. If TSIDL = 1, the
timer will resume the incrementing sequence upon
termination of the CPU Idle mode.
8.2
The input clock (F
Timer, has a prescale option of 1:1, 1:8, 1:64, and
1:256
(T1CON<5:4>). The prescaler counter is cleared when
any of the following occurs:
• a write to the TMR1 register
• clearing of the TON bit (T1CON<15>)
• device Reset such as POR
However, if the timer is disabled (TON = 0), then the
timer prescaler cannot be reset since the prescaler
clock is halted.
TMR1 is not cleared when T1CON is written. It is
cleared by writing to the TMR1 register.

During CPU Sleep mode, the timer will operate if:
• The timer module is enabled (TON = 1) and
• The timer clock source is selected as external
• The TSYNC bit (T1CON<2>) is asserted to a logic
When all three conditions are true, the timer will
continue to count up to the period register and be reset
to 0x0000.
When a match between the timer and the period regis-
ter occurs, an interrupt can be generated, if the
respective timer interrupt enable bit is asserted.
