(28) Operation when Error Occurs during Reset-Synchronized PWM Mode Operation, and
Operation is Restarted in Complementary PWM Mode
Figure 11.142 shows an explanatory diagram of the case where an error occurs in reset-
synchronized PWM mode and operation is restarted in complementary PWM mode after re-
setting.

Figure 11.142 Error Occurrence in Reset-Synchronized PWM Mode,
Recovery in Complementary PWM Mode
1 to 10 are the same as in figure 11.140.
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 cyclic output pin of this module outputs a low-level signal.)
14. Enable channel 3 and 4 output with TOER.
15. Set the multi-function timer pulse unit 2 output with the general I/O port.
16. Operation is restarted by TSTR.
