(4) Operation when Error Occurs during Normal Mode Operation, and Operation is
Restarted in Phase Counting Mode: Figure 10.88 shows an explanatory diagram of the case
where an error occurs in normal mode and operation is restarted in phase counting mode after re-
setting.

1 to 10 are the same as in Figure 10.85.
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.
