Section 18 Multi-Function Timer Pulse Unit (MTU)
(27) Operation when Error Occurs during Reset-Synchronous PWM Mode Operation, and
Figure 18.111 shows an explanatory diagram of the case where an error occurs in reset-
synchronous PWM mode and operation is restarted in PWM mode 1 after re-setting.
1 to 10 are the same as in figure 18.110.
11. Set PWM mode 1. (MTU positive phase output is low, and negative phase output is high.)
12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC *B side is not initialized.)
13. Set MTU output with the PFC.
14. Operation is restarted by TSTR.
