13.3.5 Synchronizing GP Timer Blocks
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 timeout 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 13-10 on page 969 shows the actions for the timeout event performed when the timers are
synchronized in the various timer modes.
