EXAMPLE 14-5:
14.3.8
In this mode, the timer clock source is the internal
PBCLK (Peripheral Bus Clock), TCS (TxCON<1>) = 0.
The TxCK pin provides the gating mechanism to
enable and disable the timer counting, TGATE
(TxCON<7>) = 1. The 32-bit TMRxy Count register is
enabled on the rising edge of the TxCK pin and incre-
ments on every internal PBCLK cycle when the timer
clock prescale <TCKPS> is 1:1.
The timer increments until the TMRxy Count register
matches the PRxy register value. The TMRxy Count
register resets to 0x00000000 on the next PBCLK clock
cycle. A timer match event is not generated. The timer
continues to increment and repeat the period match
until the falling edge of the TxCK pin or the timer is dis-
abled. On the falling edge of the gate signal, a timer
gate event is generated and the TMRxy Count register
stops counting, but is not reset to 0x00000000. The
TMRxy Count register must be reset in software. For
further details regarding timer events and interrupts,
see Section 14.4 Timer Interrupts.
For clock prescale = N (other than 1:1), the timer oper-
ates at a clock rate = (PBCLK/N); therefore, the TMRxy
Count register increments on every Nth timer clock
cycle. For further details regarding timer prescaler,
refer to Section 14.3.9 Timer Clock Prescaler.
The following steps should be performed to properly
configure the timer peripheral for Gated Timer mode

EXAMPLE 14-6:

Timer
(TxCON<6:4>), are used to divide the timer clock
source permitting the TMR register to increment on
every 1, 2, 4, 8, 16, 32, 64, or 256 (PBCLK or external)
clock cycles. For example, if the clock prescale is 1:8,
then the timer increments on every 8th timer clock
cycle.

Note:
timer clock prescale = N (other than 1:1), 2 to 3
external clock cycles are required, after the timer
ON bit is set = 1, before the TMRx Count register
increments.
depending on the timer clock prescale setting N
(other than 1:1), the timer will require N additional
(PBCLK or external) clock cycles before the
TMRx Counter register resets to 0x0000. Reading
the TMRx Count register just after the timer match
event, but before the TMRx Count register is
reset, will return the timer match value.
