Section 10 Multi-Function Timer Pulse Unit 2 (MTU2)
Operation when Error Occurs during Reset-Synchronized PWM Mode Operation, and
Operation is Restarted in Normal Mode: Figure 10.161 shows an explanatory diagram of the
case where an error occurs in reset-synchronized PWM mode and operation is restarted in normal
mode after re-setting.
1. After a reset, MTU2 output is low and ports are in the high-impedance state.
2. Select the reset-synchronized PWM output level and cyclic output enabling/disabling with
3. Set reset-synchronized PWM.
4. Enable channel 3 and 4 output with TOER.
5. Set MTU2 output with the PFC.
6. The count operation is started by TSTR.
7. The reset-synchronized 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. (MTU2 output becomes the reset-synchronized
11. Set normal mode. (MTU2 positive phase output is low, and negative phase output is high.)
12. Initialize the pins with TIOR.
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
