Bit 4—Output Compare Register Select (OCRS): OCRA and OCRB share the same address.
When this address is accessed, the OCRS bit selects which register is accessed. This bit does not
affect the operation of OCRA or OCRB.
Bit 3—Output Enable A (OEA): Enables or disables output of the output compare A signal
(FTOA).
Bit 2—Output Enable B (OEB): Enables or disables output of the output compare B signal
(FTOB).
Bit 1—Output Level A (OLVLA): Selects the logic level to be output at the FTOA pin in
response to compare-match A (signal indicating a match between the FRC and OCRA values).
When the OCRAMS bit is 1, this bit is ignored.
