(10) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is
Restarted in Phase Counting Mode
Figure 11.124 shows an explanatory diagram of the case where an error occurs in PWM mode 1
and operation is restarted in phase counting mode after re-setting.

Figure 11.124 Error Occurrence in PWM Mode 1, Recovery in Phase Counting Mode
1 to 10 are the same as in figure 11.121.
11. Set phase counting mode.
12. Initialize the pins with TIOR.
13. Set the multi-function timer pulse unit 2 output with the general I/O port.
14. Operation is restarted by TSTR.
Note: Phase counting mode can only be set for channels 1 and 2, and therefore TOER setting is
not necessary.
