11. Multi-Function Timer Pulse Unit (MTU)
Operation when Error Occurs during PWM Mode 1 Operation, and Operation is Restarted
in Phase Counting Mode: Figure 11.94 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.

1 to 10 are the same as in figure 11.91.
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.
