Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
(22) Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in PWM Mode 1
Figure 10.156 shows an explanatory diagram of the case where an error occurs in complementary
PWM mode and operation is restarted in PWM mode 1 after re-setting.

Figure 10.156 Error Occurrence in Complementary PWM Mode,
Recovery in PWM Mode 1
1 to 10 are the same as in figure 10.155.
11. Set PWM mode 1. (MTU2 output goes low.)
12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC *B side is not initialized.)
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
