PRE_C07-00
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
Enables the User Bits to be autobuffered between the AES3/SPDIF receiver and
transmitter
0 = The User Bits are not autobuffered
1 = The User Bits are autobuffered
Enables the Channel Status bits to be autobuffered between the AES3/SPDIF
receiver and transmitter
0 = The Channel Status bits are not autobuffered
1 = The Channel Status bits are autobuffered
Sets the maximum number of zero stuffing to be added between IUs while
autobuffering up to a maximum of 8
0000 = 0
0001 = 1
