Figure 18.99 Error Occurrence In Pwm Mode 2, Recovery In Pwm Mode 2 - Renesas HD6417641 Hardware Manual

Section 18 Multi-Function Timer Pulse Unit (MTU)
(15) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in PWM Mode 2
Figure 18.99 shows an explanatory diagram of the case where an error occurs in PWM mode 2
and operation is restarted in PWM mode 2 after re-setting.

1 to 9 are the same as in figure 18.97.
10. Not necessary when restarting in PWM mode 2.
11. Initialize the pins with TIOR. (In PWM mode 2, the cycle register pins are not initialized.)
12. Set MTU output with the PFC.
13. Operation is restarted by TSTR.
