(10) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is
Restarted in Phase Counting Mode: Figure 12.105 shows an explanatory diagram of the case
where an error occurs in PWM mode 1 and operation is restarted in phase counting mode after re-
setting.

Figure 12.105 Error Occurrence in PWM Mode 1, Recovery in Phase Counting Mode
1 to 10 are the same as in figure 12.102.
11. Set phase counting mode.
12. Initialize the pins with TIOR.
13. Set MTU output with the PFC.
14. Operation is restarted by TSTR.
Note: Phase counting mode can only be set for channels 1 and 2, and therefore TOER setting is
not necessary.
