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
(Initial value)
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
(Initial value)
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
(Initial value)
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
(Initial value)
1
High level
