00 = A-Law.
01 = µ-Law.
10 = 8-bit linear. The top 8-bits of the 16-bit linear signal are transferred, and the bottom 8-bits
are discarded.
11 = 16-bit linear. B1 and B2 channels are used for the 16-bits of data. Regardless of whether
the DAA is set to transmit and receive in the B1 or B2 channel, both channels are used to
send and receive the 16-bit linear data.
Channel B2 Enable.
0 = Channel B2 transfers are disabled.
1 = Channel B2 transfers are enabled. If 16-bit linear data format is chosen, disabling the B2
channel results in only the top 8 bits of line data being sent and received in the B1 channel.
Channel B1 Enable.
0 = Channel B1 transfers are disabled.
1 = Channel B1 transfers are enabled. If 16-bit linear data format is chosen, disabling the B1
channel results in only the bottom 8 bits of line data being sent and received in the B2 chan-
nel.
