Description
GPTM Timer A Match Register Update
Value Description
0 Update the GPTMTAMATCHR register and the GPTMTAPR
register, if used, on the next cycle.
1 Update the GPTMTAMATCHR register and the GPTMTAPR
register, if used, on the next timeout.
If the timer is disabled (TAEN is clear) when this bit is set,
GPTMTAMATCHR and GPTMTAPR are updated when the timer is
enabled. If the timer is stalled (TASTALL is set), GPTMTAMATCHR and
GPTMTAPR are updated according to the configuration of this bit.
GPTM Timer A PWM Interrupt Enable
This bit enables interrupts in PWM mode on rising, falling, or both edges
of the CCP output, as defined by the TAEVENT field in the GPTMCTL
register.
Value Description
0 Capture event interrupt is disabled.
1 Capture event interrupt is enabled.
This bit is only valid in PWM mode.
GPTM Timer A Interval Load Write
Value Description
0 Update the GPTMTAR and GPTMTAV registers with the value
in the GPTMTAILR register on the next cycle. Also update the
GPTMTAPS and GPTMTAPV registers with the value in the
GPTMTAPR register on the next cycle.
1 Update the GPTMTAR and GPTMTAV registers with the value
in the GPTMTAILR register on the next timeout. Also update
the GPTMTAPS and GPTMTAPV registers with the value in
the GPTMTAPR register on the next timeout.
Note the state of this bit has no effect when counting up.
The bit descriptions above apply if the timer is enabled and running. If
the timer is disabled (TAEN is clear) when this bit is set, GPTMTAR,
GPTMTAV and GPTMTAPs, and GPTMTAPV are updated when the
timer is enabled. If the timer is stalled (TASTALL is set), GPTMTAR and
GPTMTAPS are updated according to the configuration of this bit.
GPTM Timer A Snap-Shot Mode
Value Description
0 Snap-shot mode is disabled.
1 If Timer A is configured in the periodic mode, the actual
free-running, capture or snapshot value of Timer A is loaded at
the time-out event/capture or snapshot event into the GPTM
Timer A (GPTMTAR) register. If the timer prescaler is used,
the prescaler snapshot is loaded into the GPTM Timer A
(GPTMTAPR).
