Section 12 Multi-Function Timer Pulse Unit 2 (MTU2)
(19) Operation when Error Occurs during Phase Counting Mode Operation, and Operation
is Restarted in PWM Mode 2
Figure 12.131 shows an explanatory diagram of the case where an error occurs in phase counting
mode and operation is restarted in PWM mode 2 after re-setting.

1 to 9 are the same as in figure 12.129.
10. Set PWM mode 2.
11. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized.)
12. Set MTU2 output with the PFC.
13. Operation is restarted by TSTR.
