Pin initialization procedures are described below for the numbered combinations in table 9.59. The
active level is assumed to be low.
Operation when Error Occurs during Normal Mode Operation, and Operation is Restarted
in Normal Mode: Figure 9.124 shows an explanatory diagram of the case where an error occurs
in normal mode and operation is restarted in normal mode after re-setting.

10. The count operation is stopped by TSTR.
11. Not necessary when restarting in normal mode.
12. Initialize the pins with TIOR.
13. Set MTU2 output with the PFC.
14. Operation is restarted by TSTR.
After a reset, MTU2 output is low and ports are in the high-impedance state.
After a reset, the TMDR setting is for normal mode.
For channels 3 and 4, enable output with TOER before initializing the pins with TIOR.
Initialize the pins with TIOR. (The example shows initial high output, with low output on
compare-match occurrence.)
Set MTU2 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.
