Description
GPT Timer A PWM Interval Load Write
0h = Update the TAR register with the value in the TAILR register on
the next clock cycle. If the pre-scaler is used, update the TAPS
register with the value in the TAPR register on the next clock cycle.
1h = Update the TAR register with the value in the TAILR register on
the next timeout. If the prescaler is used, update the TAPS register
with the value in the TAPR register on the next timeout.
GPT Timer A Snap-Shot Mode
0h = Snap-shot mode is disabled.
1h = If Timer A is configured in the periodic mode, the actual free-
running value of Timer A is loaded at the time-out event into the GPT
Timer A (TAR) register.
GPT Timer A Wait-On-Trigger
0h = Timer A begins counting as soon as it is enabled.
1h = If Timer A is enabled (CTL.TAEN = 1), Timer A does not begin
counting until it receives a trigger from the timer in the previous
position in the daisy chain. This bit must be clear for GPT Module 0,
Timer A
GPT Timer A Match Interrupt Enable
0h = The match interrupt is disabled for match events. Additionally,
output triggers on match events are prevented.
1h = An interrupt is generated when the match value in TAMATCHR
is reached in the one-shot and periodic modes.
GPT Timer A Count Direction
0h = DOWN : The timer counts down.
1h = UP : The timer counts up. When counting up, the timer starts
from a value of 0x0.
GPT Timer A Alternate Mode
Note: To enable PWM mode, you must also clear TACM and then
configure TAMR field to 0x2.
0h = Capture/Compare mode is enabled.
1h = PWM mode is enabled
GPT Timer A Capture Mode
0h = EDGCNT : Edge-Count mode
1h = EDGTIME : Edge-Time mode
GPT Timer A Mode
The Timer mode is based on the timer configuration defined by CFG
1h = One-Shot Timer mode
2h = Periodic Timer mode
3h = Capture mode
