(10) Operation when Error Occurs during PWM Mode 1 Operation, and Operation is

Restarted in Phase Counting Mode: Figure 8.93 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 8.93 Error Occurrence in PWM Mode 1, Recovery in Phase Counting Mode

1 to 10 are the same as in figure 8.90.

11. Set phase counting mode.

12. Initialize the pins with TIOR.

13. Set MTU output with the PFC.

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.
