MTU2S Counter Clearing Caused by MTU2 Flag Setting Source (MTU2–MTU2S
Synchronous Counter Clearing): The MTU2S counters can be cleared by sources for setting the
flags in TSR_0 to TSR_2 in the MTU2 through the TSYCR_3 settings in the MTU2S.
1. Example of Procedure for Specifying MTU2S Counter Clearing by MTU2 Flag Setting Source
Figure 10.85 shows an example of procedure for specifying MTU2S counter clearing by
MTU2 flag setting source.
Start one of channels 0 to 2 in MTU2
