8. Multi-Function Timer Pulse Unit (MTU)
(24) Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in Complementary PWM Mode: Figure 8.107 shows an explanatory
diagram of the case where an error occurs in complementary PWM mode and operation is
restarted in complementary PWM mode after re-setting (when operation is restarted using
completely new cycle and duty cycle settings).

Complementary PWM Mode
1 to 10 are the same as in figure 8.104.
11. Set normal mode and make new settings. (MTU output goes low.)
12. Disable channel 3 and 4 output with TOER.
13. Select the complementary PWM mode output level and cyclic output enabling/disabling with
TOCR.
14. Set complementary PWM.
15. Enable channel 3 and 4 output with TOER.
16. Set MTU output with the PFC.
17. Operation is restarted by TSTR.
