Figure 18.112 Error Occurrence In Reset-Synchronous Pwm Mode, Recovery In Complementary Pwm Mode - Renesas HD6417641 Hardware Manual

(28) Operation when Error Occurs during Reset-Synchronous PWM Mode Operation, and
Operation is Restarted in Complementary PWM Mode
Figure 18.112 shows an explanatory diagram of the case where an error occurs in reset-
synchronous PWM mode and operation is restarted in complementary PWM mode after re-setting.

11. Disable channel 3 and 4 output with TOER.
12. Select the complementary PWM output level and cyclic output enabling/disabling with
TOCR.
13. Set complementary PWM. (The MTU cyclic output pin goes low.)
14. Enable channel 3 and 4 output with TOER.
15. Set MTU output with the PFC.
16. Operation is restarted by TSTR.
