Stellaris® LM3S5737 Microcontroller
Register 4: GPTM Control (GPTMCTL), offset 0x00C
This register is used alongside the GPTMCFG and GMTMTnMR registers to fine-tune the timer
configuration, and to enable other features such as timer stall and the output trigger. The output
trigger can be used to initiate transfers on the ADC module.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
GPTM TimerB PWM Output Level
The TBPWML values are defined as follows:
Value Description
0 Output is unaffected.
1 Output is inverted.

GPTM TimerB Output Trigger Enable
The TBOTE values are defined as follows:
Value Description
0 The output TimerB ADC trigger is disabled.
1 The output TimerB ADC trigger is enabled.
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 473).
