(3) Operation when Error Occurs during Normal Mode Operation, and Operation is
Restarted in PWM Mode 2:
Figure 12.98 shows an explanatory diagram of the case where an
error occurs in normal mode and operation is restarted in PWM mode 2 after re-setting.

Figure 12.98 Error Occurrence in Normal Mode, Recovery in PWM Mode 2
1 to 10 are the same as in figure 12.96.
11. Set PWM mode 2.
12. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized. If
initialization is required, initialize in normal mode, then switch to PWM mode 2.)
13. Set MTU output with the PFC.
14. Operation is restarted by TSTR.
Note:
PWM mode 2 can only be set for channels 0–2, and therefore TOER setting is not
necessary.
