(17) Operation when Error Occurs during Phase Counting Mode Operation, and Operation
Figure 12.141 shows an explanatory diagram of the case where an error occurs in phase counting
mode and operation is restarted in normal mode after re-setting.
1. After a power-on reset, MTU2 output is low and ports are in the high-impedance state.
2. Set phase counting mode.
3.
4. Set MTU2 output with the PFC.
5. The count operation is started by TSTR.
6. Output goes low on compare-match occurrence.
7. An error occurs.
8. Set port output with the PFC and output the inverse of the active level.
9. The count operation is stopped by TSTR.
10. Set in normal mode.
11. Initialize the pins with TIOR.
12. Set MTU2 output with the PFC.
13. Operation is restarted by TSTR.
