Section 18 Multi-Function Timer Pulse Unit (MTU)
(25) Operation when Error Occurs during Complementary PWM Mode Operation, and
Figure 18.109 shows an explanatory diagram of the case where an error occurs in complementary
PWM mode and operation is restarted in reset-synchronous PWM mode.
1 to 10 are the same as in figure 18.105.
11. Set normal mode. (MTU output goes low.)
12. Disable channel 3 and 4 output with TOER.
13. Select the reset-synchronous PWM mode output level and cyclic output enabling/disabling
14. Set reset-synchronous PWM.
15. Enable channel 3 and 4 output with TOER.
16. Set MTU output with the PFC.
17. Operation is restarted by TSTR.
