REGISTER BITS BY ADDRESS
Register 00h is a read-only register. Writing any value to this register resets all registers to their default, but does not
change the contents of reg. 00h. Reading the register reveals information about the CODEC to the driver, as required by the
AC’97 Specification, Revision 2.2
Register 02h controls the output pins LOUT2 and ROUT2.
Register 04h controls the headphone output pins, HPOUTL and HPOUTR.
Register 06h controls the analogue output pin MONOOUT.
