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 (
the timer is disabled (
TBEN
is clear) when this bit is set, GPTMTBR,
GPTMTBV and are updated when the timer is enabled. If the timer is
stalled (
stalled (
TBSTALL

GPTM Timer B Snap-Shot Mode
Description
Value
Snap-shot mode is disabled.
0
If Timer B is configured in the periodic mode, the actual
free-running value of Timer B is loaded at the time-out event
into the GPTM Timer B (GPTMTBR) register. If the timer
prescaler is used, the prescaler snapshot is loaded into the
GPTM Timer B (GPTMTBPR).

GPTM Timer B Wait-on-Trigger
Description
Value
Timer B begins counting as soon as it is enabled.
0
If Timer B is enabled (
TBEN
is set in the GPTMCTL register),
Timer B does not begin counting until it receives a trigger from
the timer in the previous position in the daisy chain, see . This
function is valid for one-shot, periodic, and PWM modes.

Description
Value
The match interrupt is disabled for match events. Additionally,
triggers to the DMA and ADC on match events are prevented.
triggers to the DMA and ADC on match events are prevented.
0
An interrupt is generated when the match value in the
GPTMTBMATCHR register is reached in the one-shot and
periodic modes.
