10.18 User Data Buffer Control (13h)
UD User data pin (U) direction specifier
0 - The U pin is an input. The U data is latched in on both rising and falling edges of
OLRCK. This setting also chooses the U pin as the source for transmitted
U data (default).
1 - The U pin is an output. The received U data is clocked out on both rising and falling edges
of ILRCK. This setting also chooses the U data buffer as the source of transmitted
U data.
UBM[1:0] Sets the operating mode of the AES3 U bit manager
00 - Transmit all zeros mode (default)
01 - Block mode
10 - Reserved
11 - IEC consumer mode B
DETUI D to E U-data buffer transfer inhibit bit (valid in block mode only).
0 - Allow U-data D to E buffer transfers (default)
1 - Inhibit U-data D to E buffer transfers
EFTUI E to F U-data buffer transfer inhibit bit (valid in block mode only).
0 - Allow U-data E to F buffer transfers (default)
1 - Inhibit U-data E to F buffer transfer
Q-Channel Subcode Bytes 0 to 9 (14h - 1Dh) (Read Only)
The following 10 registers contain the decoded Q-channel subcode data
Each byte is LSB first with respect to the 80 Q-subcode bits Q[79:0]. Thus bit 7 of address 14h is Q[0] while
bit 0 of address 14h is Q[7]. Similarly bit 0 of address 1Dh corresponds to Q[79].
