(16) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in Phase Counting Mode
Figure 18.100 shows an explanatory diagram of the case where an error occurs in PWM mode 2
and operation is restarted in phase counting mode after re-setting.

1 to 9 are the same as in figure 18.97.
10. Set phase counting mode.
11. Initialize the pins with TIOR.
12. Set MTU output with the PFC.
13. Operation is restarted by TSTR.
