(22) Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in PWM Mode 1
Figure 11.136 shows an explanatory diagram of the case where an error occurs in complementary
PWM mode and operation is restarted in PWM mode 1 after re-setting.

Figure 11.136 Error Occurrence in Complementary PWM Mode,
Recovery in PWM Mode 1
1 to 10 are the same as in figure 11.135.
11. Set PWM mode 1. (This module outputs a low-level signal.)
12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC *B side is not initialized.)
13. Set the multi-function timer pulse unit 2 output with the general I/O port.
14. Operation is restarted by TSTR.
