(14) Operation when Error Occurs during PWM Mode 2 Operation, and Operation is
Restarted in PWM Mode 1
Figure 11.128 shows an explanatory diagram of the case where an error occurs in PWM mode 2
and operation is restarted in PWM mode 1 after re-setting.

1 to 9 are the same as in figure 11.127.
10. Set PWM mode 1.
11. Initialize the pins with TIOR. (In PWM mode 1, the TIOC*B side is not initialized.)
12. Set the multi-function timer pulse unit 2 output with the general I/O port.
13. Operation is restarted by TSTR.
