GPTM Timer A Output Trigger Enable
The TAOTE values are defined as follows:
DescriptionValue
The output Timer A ADC trigger is disabled.0
The output Timer A ADC trigger is enabled.1
In addition, the ADC must be enabled and the timer selected as a trigger
source with the EMn bit in the ADCEMUX register (see page 1091).
0RWTAOTE5
GPTM RTC Stall Enable
The RTCEN values are defined as follows:
DescriptionValue
RTC counting freezes while the processor is halted by the
debugger.
0
RTC counting continues while the processor is halted by the
debugger.
1
If the RTCEN bit is set, it prevents the timer from stalling in all operating
modes, even if TnSTALL is set.
0RWRTCEN4
GPTM Timer A Event Mode
The TAEVENT values are defined as follows:
DescriptionValue
Positive edge0x0
Negative edge0x1
Reserved0x2
Both edges0x3
Note: If PWM output inversion is enabled, edge detection interrupt
behavior is reversed. Thus, if a positive-edge interrupt trigger
has been set and the PWM inversion generates a postive
edge, no event-trigger interrupt asserts. Instead, the interrupt
is generated on the negative edge of the PWM signal.
0x0RWTAEVENT3:2
GPTM Timer A Stall Enable
The TASTALL values are defined as follows:
DescriptionValue
Timer A continues counting while the processor is halted by the
debugger.
0
Timer A freezes counting while the processor is halted by the
debugger.
1
If the processor is executing normally, the TASTALL bit is ignored.
