Operation when Error Occurs during Normal Mode Operation, and Operation is Restarted
in Complementary PWM Mode: Figure 10.89 shows an explanatory diagram of the case where
an error occurs in normal mode and operation is restarted in complementary PWM mode after re-
setting.

1 to 10 are the same as in Figure 10.85.
11. Initialize the normal mode waveform generation section with TIOR.
12. Disable operation of the normal mode waveform generation section with TIOR.
13. Disable channel 3 and 4 output with TOER.
14. Select the complementary PWM output level and cyclic output enabling/disabling with
TOCR.
15. Set complementary PWM.
16. Enable channel 3 and 4 output with TOER.
17. Set MTU output with the PFC.
18. Operation is restarted by TSTR.
