[1] Select 0 output, 1 output, or toggle output for
compare match output by means of TRGIOR.
[2] Set the timing for compare match generation in
GRA/GRB.
[3] Write the same value output initially from the
compare match output pin (TGIOA or TGIOB) to
the PDR bit of the corresponding pin specified
by the PMC.
[4] When the PMR bit of the corresponding pin
specified by the PMC is set to 1, the port
functions as the compare match output pin.
[5] Set the STR bit in TRGMDR to 1 to start the
TRGCNT count operation.

Note: * When the initial toggled output immediately after release from the reset state is
selected. In case where switching was from another output, the output value is that
which preceded the switch.
