Figure 8.100 Error Occurrence in Phase Counting Mode, Recovery in Normal Mode

After a reset, MTU output is low and ports are in the high-impedance state.

Set phase counting mode.

Initialize the pins with TIOR. (The example shows initial high output, with low output on

compare-match occurrence.)

Set MTU output with the PFC.

The count operation is started by TSTR.

Output goes low on compare-match occurrence.

An error occurs.

Set port output with the PFC and output the inverse of the active level.

The count operation is stopped by TSTR.

10. Set in normal mode.

11. Initialize the pins with TIOR.

12. Set MTU output with the PFC.

13. Operation is restarted by TSTR.
