Section 10 16-Bit Integrated Timer Pulse Unit (ITU)
Compare-Match Waveform Output Function: For ITU channels 0, 1, 3, and 4, the output from
the corresponding TIOCA and TIOCB pins upon compare matches A and B can be in three
modes: 0-level output, 1-level output, or toggle. Toggle output cannot be selected for channel 2.

Procedure for selecting the waveform output mode (figure 10.19):
1. Set TIOR to select 0 output, 1 output, or toggle output for compare match output. The
2. Set a value in GRA or GRB to select the compare match timing.
3.
