Section 10 Multi-Function Timer Pulse Unit 2 (MTU2) and Multi-Function Timer Pulse Unit 2S (MTU2S)
Operation when Error Occurs during PWM Mode 1 Operation, and Operation is Restarted
in Phase Counting Mode: Figure 10.146 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.

1 to 10 are the same as in figure 10.143.
11. Set phase counting mode.
12. Initialize the pins with TIOR.
13. Set MTU2 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.
