(18) Operation when Error Occurs during Phase Counting Mode Operation, and Operation
is Restarted in PWM Mode 1
Figure 11.132 shows an explanatory diagram of the case where an error occurs in phase counting
mode and operation is restarted in PWM mode 1 after re-setting.

Figure 11.132 Error Occurrence in Phase Counting Mode, Recovery in PWM Mode 1
1 to 9 are the same as in figure 11.131.
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.
