Table 48. Autobuffer Register Bit Descriptions
Bit Name Description
Zero_Stuff_IU Enables the addition or subtraction of zeros between IUs during autobuffering of the user bits in IEC60958-3 format.
0 = No zeros added or subtracted.
1 = Zeros can be added or subtracted between IUs.
Auto_UBits Enables the user bits to be autobuffered between the AES3/S/PDIF receiver and transmitter.
0 = User bits are not autobuffered.
1 = User bits are autobuffered.
Auto_CSBits Enables the channel status bits to be autobuffered between the AES3/S/PDIF receiver and transmitter.
0 = Channel status bits are not autobuffered.
1 = Channel status bits are autobuffered.
IU_Zeros[3:0] Sets the maximum number of zero-stuffing to be added between IUs while autobuffering up to a maximum of 8.
0000 = 0.
0001 = 1.
…
0111 = 7.
1000 = 8.
