Section 10 Multi-Function Timer Pulse Unit (MTU)
(18) Operation when Error Occurs during Phase Counting Mode Operation, and Operation
is Restarted in PWM Mode 1: Figure 10.102 shows an explanatory diagram of the case where an
error occurs in phase counting mode and operation is restarted in PWM mode 1 after re-setting.

1 to 9 are the same as in Figure 10.101.
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.
