previous value. This comparison is made at every fs cycle. This bit returns to “L” by reading
Receiver Status 1(03H). The flag is disabled during the first block after Reset.
96kHz Sampling Detect at Recovery Mode.
0: fs=54kHz or less.
1: fs=88.2kHz or more
Sampling Frequency Output
Pre-emphasis Output
0: OFF
1: ON
This bit is made by encoding channel status bits.
Non-PCM Auto Detect
0: No detect
1: Detect
This function is the same as AUTO pin.
0: Audio
1: Non Audio
Unlock or Parity Error or Status change
0: No Error or No change
1: Error or Change
This function is the same as ERF pin. This bit goes “1” when Unlock Error, Parity Error, Biphase
Error, Frame Length Error or Status Change occurs. If MPAR=0 & MSTC=0, only an unlock error
is reported.
Parity Status (0:No Error, 1:Error)
It is high if Parity Error is detected in the sub-frame. PAR is unaffected by the state of MPAR.
Biphase Status (0:No Error, 1:Error)
Validity bit (0:No Error, 1:Error)
Cyclic Redundancy Check (0:No Error, 1:Error on either channel)
Status change flag of Receiver status 1 (0:No change, 1:change)
This flag goes “H” when the latest value of D5-0 in Receiver Status 1(03H) is different from the
Channel Status Validity (0:Valid, 1:Not Valid, data is updating)
This signal goes “H” at the start of frame 0 and maintains “H” until the end of frame 31.
