(18) Operation when Error Occurs during Phase Counting Mode Operation, and Operation
is Restarted in PWM Mode 1
Figure 8.101 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 8.100.
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.
(19) Operation when Error Occurs during Phase Counting Mode Operation, and Operation
is Restarted in PWM Mode 2
Figure 8.102 shows an explanatory diagram of the case where an error occurs in phase counting
mode and operation is restarted in PWM mode 2 after re-setting.
