Section 11 Multi-Function Timer Pulse Unit 2 (MTU2)
SH7080 Group
Operation when Error Occurs during Normal Mode Operation, and Operation is Restarted
in Reset-Synchronized PWM Mode: Figure 11.144 shows an explanatory diagram of the case
where an error occurs in normal mode and operation is restarted in reset-synchronized PWM mode
after re-setting.

1 to 13 are the same as in figure 11.139.
14. Select the reset-synchronized PWM output level and cyclic output enabling/disabling with
TOCR.
15. Set reset-synchronized PWM.
16. Enable channel 3 and 4 output with TOER.
17. Set MTU2 output with the PFC.
18. Operation is restarted by TSTR.
