The GPTM Synchronizer Control (GPTMSYNC) register in the GPTM0 block can be used to synchronize selected timers to begin counting at the same time. Setting a bit in the GPTMSYNC register causes the associated timer to perform the actions of a time-out event. An interrupt is not generated when the timers are synchronized. If a timer is being used in concatenated mode, only the bit for Timer A must be set in the GPTMSYNC register.
NOTE
All timers must use the same clock source for this feature to work correctly.
Table 18-9 lists the actions for the time-out event performed when the timers are synchronized in the various timer modes.
| Mode | Count Direction | Time-Out Action |
|---|---|---|
| 32-bit one-shot (concatenated timers) | – | N/A |
| 32-bit periodic (concatenated timers) | Down | Count value = ILR |
| Up | Count value = 0 | |
| 32-bit RTC (concatenated timers) | Up | Count value = 0 |
| 16-bit one shot (individual/split timers) | – | N/A |
| 16-bit periodic (individual/split timers) | Down | Count value = ILR |
| Up | Count value = 0 | |
| 16-bit edge count (individual/split timers) | Down | Count value = ILR |
| Up | Count value = 0 | |
| 16-bit edge time (individual/split timers) | Down | Count value = ILR |
| Up | Count value = 0 | |
| 16-bit PWM | Down | Count value = ILR |
