The Function Code Bits are used to read Register 68h (Page 01h) and Register
6Ah (Page 01h).
Mono I/O should report relevant sense and function information on Tip, and report
not supported on Ring.
Setting the function code to unsupported values will return a 0 when accessing the
Information Valid Bit in page 01 register 68h bit 5.
Tip or Ring selection Bit.This bit sets which jack conductor the sense value is
measured from. Software will program the corresponding the Ring/Tip selector bit
together with the I/O number in bits FC[3:0].
