Section 8 Multifunction Timer Pulse Unit (MTU)
(5) Operation when Error Occurs during Normal Mode Operation, and Operation is
Restarted in Complementary PWM Mode
Figure 8.88 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.

Figure 8.88 Error Occurrence in Normal Mode, Recovery in Complementary PWM Mode
1 to 10 are the same as in figure 8.84.
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.
