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.

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

Start channel 3 or 4 in MTU2S

[1] Use TSTR registers in the MTU2 and MTU2S and halt the

counters used for this function.

[2] Use TSYCR_3 in the MTU2S to specify the flag setting source

to be used for the TCNT_3 and TCNT_4 clearing source.

[3] Start TCNT_3 or TCNT_4 in the MTU2S.

[4] Start TCNT_0, TCNT_1, or TCNT_2 in the MTU2.

Note: The TSYCR_3 setting is ignored while the counter is

stopped. The setting becomes valid after TCNT_3 or

TCNT4 is started.
