Bit 4    Selecting the Output Comparing Register (OCRS): The addresses of the OCRA and
OCRB are the same. The OCRS works to control which register to choose when reading/writing
this address. The choice will not influence the operation of the OCRA and OCRB.
Bit 4
OCRS Description
0 Selects the OCRA register
1 Selects the OCRB register
Bit 3    Enabling the Output A (OEA): This bit works to control the output comparing A signals.
Bit 3
OEA Description
0 Prohibits the output comparing A signal outputs
1 Permits the output comparing A signal outputs
Bit 2    Enabling the Output B (OEB): This bit works to control the output comparing B signals.
Bit 2
OEB Description
0 Prohibits the output comparing B signal outputs
1 Permits the output comparing B signal outputs
Bit 1    Output Level A (OLVLA): This bit works to select the output level to output through the
FTOA pin by use of the comparing match A (matching signal between the FRC and OCRA).
Bit 1
OLVLA Description
0 Low level
1 High level
