Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) and Multi-Function Timer Pulse Unit 2S (MTU2S)
2. Examples of Synchronous Counter Start Operation
Figures 10.85 (1), 10.85 (2), 10.85 (3), and 10.85 (4) shows examples of synchronous counter
start operation when the clock frequency ratio between the MTU2 and MTU2S is 1:1, 1:2, 1:3,
and 1:4, respectively.
In these examples, the counter clock of the MTU2 is MPφ/1.
