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
