Operation when Error Occurs during Reset-Synchronous PWM Mode Operation, and
Operation is Restarted in Normal Mode: Figure 11.110 shows an explanatory diagram of the
case where an error occurs in reset-synchronous PWM mode and operation is restarted in normal
mode after re-setting.
1. After a reset, MTU output is low and ports are in the high-impedance state.
2. Select the reset-synchronous PWM output level and cyclic output enabling/disabling with
3. Set reset-synchronous PWM.
4. Enable channel 3 and 4 output with TOER.
5. Set MTU output with the PFC.
6. The count operation is started by TSTR.
7. The reset-synchronous PWM waveform is output on compare-match occurrence.
8. An error occurs.
9. Set port output with the PFC and output the inverse of the active level.
10. The count operation is stopped by TSTR. (MTU output becomes the reset-synchronous PWM
11. Set normal mode. (MTU positive phase output is low, and negative phase output is high.)
12. Initialize the pins with TIOR.
13. Set MTU output with the PFC.
14. Operation is restarted by TSTR.
