Section 12 Multi-Function Timer Pulse Unit 2 (MTU2)
(24) Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in Complementary PWM Mode
Figure 12.148 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 settings).

Recovery in Complementary PWM Mode
1 to 10 are the same as in figure 12.145.
11. Set normal mode and make new settings. (MTU2 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 MTU2 output with the PFC.
17. Operation is restarted by TSTR.
