The above applies under the following conditions:
The EBi bit in the TRDOER1 register is set to 0 (enable TRDIOBi output).
The POLB bit in the TRDPOCRi register is set to 0 (active level “L”).

When compare matches with registers TRDGRAi and TRDGRBi are generated
simultaneously, the compare match with the TRDGRBi register has priority.
“L” is applied to the TRDIOBi output without any change.

Duty 0%
“L” is applied to TRDIOBi output at compare match
with the TRDGRBi register with no change.

m: Value set in TRDGRAi register
Since no compare match in the TRDGRBi register is
generated, “L” is not applied to the TRDIOBi output
