Section 10 16-Bit Integrated Timer Unit (ITU)
Waveform Output by Compare Match
In ITU channels 0, 1, 3, and 4, compare match A or B can cause the output at the TIOCA or
TIOCB pin to go to 0, go to 1, or toggle. In channel 2 the output can only go to 0 or go to 1.
Sample setup procedure for waveform output by compare match: Figure 10.19 shows a
sample procedure for setting up waveform output by compare match.

Select the compare match output mode (0, 1, or
toggle) in TIOR. When a waveform output mode
is selected, the pin switches from its generic input/
output function to the output compare function
(TIOCA or TIOCB). An output compare pin outputs
0 until the first compare match occurs.
Set a value in GRA or GRB to designate the
compare match timing.
Set the STR bit to 1 in TSTR to start the timer
counter.
