(27) Operation when Error Occurs during Reset-Synchronized PWM Mode Operation, and
Operation is Restarted in PWM Mode 1
Figure 11.141 shows an explanatory diagram of the case where an error occurs in reset-
synchronized PWM mode and operation is restarted in PWM mode 1 after re-setting.

Figure 11.141 Error Occurrence in Reset-Synchronized PWM Mode,
Recovery in PWM Mode 1
1 to 10 are the same as in figure 11.140.
11. Set PWM mode 1. (The positive phase output from this module is low, and negative phase
output is high.)
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.
