Operation when Error Occurs during Complementary PWM Mode Operation, and
Operation is Restarted in Normal Mode: Figure 11.105 shows an explanatory diagram of the
case where an error occurs in complementary 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 complementary PWM output level and cyclic output enabling/disabling with
3. Set complementary 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 complementary 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 complementary PWM
11. Set normal mode. (MTU output goes low.)
12. Initialize the pins with TIOR.
13. Set MTU output with the PFC.
14. Operation is restarted by TSTR.
