10.4.10 MTU2–MTU2S Synchronous Operation
MTU2–MTU2S Synchronous Counter Start: The counters in the MTU2 and MTU2S which
operate at different clock systems can be started synchronously by making the TCSYSTR settings
in the MTU2.
1. Example of MTU2–MTU2S Synchronous Counter Start Setting Procedure
Figure 10.83 shows an example of synchronous counter start setting procedure.
