Section 18 Multi-Function Timer Pulse Unit (MTU)
(11) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is
Restarted in Complementary PWM Mode
Figure 18.95 shows an explanatory diagram of the case where an error occurs in PWM mode 1
and operation is restarted in complementary PWM mode after re-setting.

1 to 10 are the same as in figure 18.91.
11. Set normal mode for initialization of the normal mode waveform generation section.
12. Initialize the PWM mode 1 waveform generation section with TIOR.
13. Disable operation of the PWM mode 1 waveform generation section with TIOR.
14. Disable channel 3 and 4 output with TOER.
15. Select the complementary PWM output level and cyclic output enabling/disabling with
TOCR.
16. Set complementary PWM.
17. Enable channel 3 and 4 output with TOER.
18. Set MTU output with the PFC.
19. Operation is restarted by TSTR.
