Advanced modem/audio analog front-end

6.7.1
The first 64 bits in the sib-frame are read and written by the
UCB1100 and they contain both audio and telecom codec data
fields, several control bits and a control register data field as is
defined in table below.
SIB Data Format
Sib frame bit
SIBDin
field definition
SIBDout
field definition
15–0
audio input path data [15:0];
bit 0 = MSB,
the 12 MSB bits are read.
audio output path data [15:0];
bit 0 = MSB,
the bits [15:12] are ‘0’
16
not read but reserved
fixed ‘0’
20–17
control register address [3:0];
bit 0 = MSB
control register address [3:0];
bit 0 = MSB;
= copy of the register address as present in
the sibdin field in the
same
sib frame
21
write bit (write = 1)
fixed zero
29–22
not read but reserved
fixed zeros
30
audio valid sample flag
audio valid flag
31
telecom valid sample flag
telecom valid flag
47–32
telecom input path data [15:0];
bit 0 = MSB,
the 14 MSB bits are read.
telecom output path data [15:0],
bit 0 = MSB,
the bits [15:14] are ‘0’’
63–48
control register ‘write data [15:0];
bit 0 = MSB
control register read data [15:0];
bit 0 = MSB
NOTE:
Since the data transfer is completely synchronous, a given control register may be written many times, before the device feeding the data has a
chance to change the control bits. The UCB1100 does detect whether the data is changed or not.
