Section 9 Multi-Function Timer Pulse Unit 2 (MTU2)
Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in Reset-Synchronized PWM Mode: Figure 9.148 shows an
explanatory diagram of the case where an error occurs in complementary PWM mode and
operation is restarted in reset-synchronized PWM mode after re-setting.

1 to 10 are the same as in figure 9.144.
11. Set normal mode. (MTU2 output goes low.)
12. Disable channel 3 and 4 output with TOER.
13. Select the reset-synchronized PWM mode output level and cyclic output enabling/disabling
with TOCR.
14. Set reset-synchronized PWM.
15. Enable channel 3 and 4 output with TOER.
16. Set MTU2 output with the PFC.
17. Operation is restarted by TSTR.
