Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
Operation when Error Occurs during Normal Mode Operation, and Operation is Restarted
in PWM Mode 1: Figure 10.137 shows an explanatory diagram of the case where an error occurs
in normal mode and operation is restarted in PWM mode 1 after re-setting.

1 to 10 are the same as in figure 10.136.
11. Set PWM mode 1.
12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized. If
initialization is required, initialize in normal mode, then switch to PWM mode 1.)
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
