sponding bits in Interrupt 2 register. This register defaults to 00h.

Interrupt 2 Mode MSB (0Dh) and Interrupt 2 Mode LSB(0Eh)

The two Interrupt Mode registers form a 2-bit code for each Interrupt Register 1 function. There are three ways to

set the INT pin active in accordance with the interrupt condition. In the Rising edge active mode, the INT pin be-

comes active on the arrival of the interrupt condition. In the Falling edge active mode, the INT pin becomes active

on the removal of the interrupt condition. In Level active mode, the INT interrupt pin becomes active during the in-

terrupt condition. Be aware that the active level(Actice High or Low) only depends on the INT[1:0] bits. These regis-

ters default to 00.

00 - Rising edge active

01 - Falling edge active

10 - Level active

11 - Reserved

Receiver Channel Status (0Fh) (Read Only)

The bits in this register can be associated with either channel A or B of the received data. The desired channel is

selected with the CHS bit of the Channel Status Data Buffer Control Register.

AUX3:0 - Incoming auxiliary data field width, as indicated by the incoming channel status bits, de-

coded according to IEC60958 and AES3.

0000 - Auxiliary data is not present

0001 - Auxiliary data is 1 bit long

0010 - Auxiliary data is 2 bits long

0011 - Auxiliary data is 3 bits long

0100 - Auxiliary data is 4 bits long

0101 - Auxiliary data is 5 bits long

0110 - Auxiliary data is 6 bits long

0111 - Auxiliary data is 7 bits long

1000 - Auxiliary data is 8 bits long

1001 - 1111 Reserved

PRO - Channel status block format indicator

0 - Received channel status block is in consumer format

1 - Received channel status block is in professional format

AUDIO - Audio indicator

0 - Received data is linearly coded PCM audio

1 - Received data is not linearly coded PCM audio

COPY - SCMS copyright indicator

0 - Copyright asserted

1 - Copyright not asserted

If the category code is set to General in the incoming AES3 stream, copyright will always be indicated by COPY,

even when the stream indicates no copyright.
