(25) Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in Reset-Synchronized PWM Mode
Figure 11.139 shows an explanatory diagram of the case where an error occurs in complementary
PWM mode and operation is restarted in reset-synchronized PWM mode.

Figure 11.139 Error Occurrence in Complementary PWM Mode,
Recovery in Reset-Synchronized PWM Mode
1 to 10 are the same as in figure 11.135.
11. Set normal mode. (This module outputs a low-level signal.)
12. Disable channel 3 and 4 output with TOER.
13. Select the reset-synchronized PWM mode output level and cyclic output enabling/disabling
with TOCR.
14. Set reset-synchronized PWM.
15. Enable channel 3 and 4 output with TOER.
16. Set the multi-function timer pulse unit 2 output with the general I/O port.
17. Operation is restarted by TSTR.
