AUX Port Configuration (Address 03h)
Enable Aux Serial Port (EnAuxPort)
Default = 0
Function:
Controls the operation of the auxiliary serial port.
Delay & Warning Port Configuration (DlyPortCfg[1:0])
Default = 00
Function:
Controls the operation of the delay and warning port. See
page 44
Aux/Delay Serial Port Digital Interface Format (AuxI²S/LJ)
Default = 0
Function:
Selects the serial audio interface format for the data on AUX_SDOUT, DLY_SDIN, DLY_SDOUT. The re-
quired relationship between the Left/Right clock, serial clock and serial data is defined by the Digital In-
terface Format and the options are detailed in the
Aux Serial Port Right Channel Data Select (RChDSel[1:0])
Default = 01
Function:
Selects the data to be sent over the right channel of the auxiliary port serial data output signal.
