Description
Most significant byte of the number of zeros to be stuffed between IEC60958-3 messages (packets).
Default = 0x00.
Description
Least significant byte of the number of zeros to be stuffed between IEC60958-3 messages (packets). Default = 0x09.
Description
Enables the addition or subtraction of zeros between IUs during autobuffering of the user bits in IEC60958-3 format.
Enables the user bits to be autobuffered between the AES3/S/PDIF receiver and transmitter.
Enables the channel status bits to be autobuffered between the AES3/S/PDIF receiver and transmitter.
Sets the maximum number of zero-stuffing to be added between IUs while autobuffering up to a maximum of 8.
Description
Seven most significant bits of the15-bit sample rate ratio.
0 = No zeros added or subtracted.
1 = Zeros can be added or subtracted between IUs.
0 = User bits are not autobuffered.
1 = User bits are autobuffered.
0 = Channel status bits are not autobuffered.
1 = Channel status bits are autobuffered.
0000 = 0.
0001 = 1.
…
0111 = 7.
1000 = 8.
