Operation when Error Occurs during PWM Mode 2 Operation, and Operation is Restarted
in Phase Counting Mode: Figure 9.139 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 9.136.
10. Set phase counting mode.
11. Initialize the pins with TIOR.
12. Set MTU2 output with the PFC.
13. Operation is restarted by TSTR.
