The above applies under the following conditions:
• The EB bit in the TRCOER register is set to 0 (output from TRCIOB enabled).
• The POLB bit in the TRCCR2 register is set to 0 (“L” active).

If compare matches occur simultaneously with registers TRCGRA and
TRCGRB, the compare match with the TRCGRB register has priority.
TRCIOB output switches to “L”. (In other words, no change).

Duty 0%
TRCIOB output switches to “L” at compare match with the
TRCGRB register. (In other words, no change).
m: TRCGRA register setting value

TRCIOB output does not switch to “L” because
no compare match with the TRCGRB register
