Section 12 Multi-Function Timer Pulse Unit 2 (MTU2)
(9) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is
Restarted in PWM Mode 2
Figure 12.133 shows an explanatory diagram of the case where an error occurs in PWM mode 1
and operation is restarted in PWM mode 2 after re-setting.

1 to 10 are the same as in figure 12.131.
11. Set PWM mode 2.
12. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized.)
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
Note: PWM mode 2 can only be set for channels 0 to 2, and therefore TOER setting is not
necessary.
