(2) Operation when Error Occurs during Normal Mode Operation, and Operation is
Restarted in PWM Mode 1
Figure 11.116 shows an explanatory diagram of the case where an error occurs in normal mode
and operation is restarted in PWM mode 1 after re-setting.

Figure 11.116 Error Occurrence in Normal Mode, Recovery in PWM Mode 1
1 to 10 are the same as in figure 11.115.
11. Set PWM mode 1.
12. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized. If
initialization is required, initialize in normal mode, and then switch to PWM mode 1.)
13. Set the multi-function timer pulse unit 2 output with the general I/O port.
14. Operation is restarted by TSTR.
