Section 8 Multifunction Timer Pulse Unit (MTU)
(14) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in PWM Mode 1
Figure 8.97 shows an explanatory diagram of the case where an error occurs in PWM mode 2 and
operation is restarted in PWM mode 1 after re-setting.

1 to 9 are the same as in figure 8.96.
10. Set PWM mode 1.
11. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized.)
12. Set MTU output with the PFC.
13. Operation is restarted by TSTR.
(15) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in PWM Mode 2
Figure 8.98 shows an explanatory diagram of the case where an error occurs in PWM mode 2 and
operation is restarted in PWM mode 2 after re-setting.
