The AK4114 can output either the through output(from DIR) or transmitter output(DIT; the data from DAUX is
transformed to IEC60958 format.) from TX1/0 pins. Those could be selected by DIT bit. The source of the through
output from TX0 could be selected among RX0-8 by OPS00,01 and 02 bits, for TX1, by OPS10,11 and 12 bits
respectively. When output DAUX data, V bit could be controlled by VIN pin and first 5 bytes of C bit could be controlled
by CT39-CT0 bits in control registers. When bit0= “0”(consumer mode), bit20-23(Audio channel) could not be
controlled directly but be controlled by CT20 bit. When the CT20 bit is “1”, AK4114 outputs “1000” as C20-23 for left
channel and output “0100” at C20-23 for right channel automatically. When CT20 bit is “0”, AK4114 outputs “0000” set
as “1000” for sub frame 1, and “0100” for sub frame 2. U bits are fixed to “0”.as C20-23 for both channel. U bit could be
controlled by UDIT bit as follows; When UDIT bit is “0”, U bit is always “L”. When UDIT bit is “1”, the recovered U
bits are used for DIT( DIR-DIT loop mode of U bit). This mode is only available when PLL is locked and the master
mode.
