Data Sheet
88
Zarlink Semiconductor Inc.
When CMM is one, the device is programmed to perform one of the special per-channel transmission modes. Bits
PCC0 and PCC1 from connection memory are used to select the per-channel tristate, message or BER test mode
as shown in Table 54 on page 88.
Bit
Name
Description
15
UAEN
Conversion between
μ
-law and A-law Enable (Message mode only)
When this bit is low, message mode has no
μ
-law/A-law conversion. Connec-
tion memory high will be ignored.
When this bit is high, message mode has
μ
-law/A-law conversion, and con-
nection memory high controls the conversion method.
14 - 11
Unused
Reserved
In normal functional mode, these bits
MUST
be set to zero.
10 - 3
MSG7 - 0
Message Data Bits
8-bit data for the message mode. Not used in the per-channel tristate and
BER test modes.
2 - 1
PCC1 - 0
Per-Channel Control Bits
These two bits control the corresponding entry’s value on the STio stream
.
0
CMM = 1
Connection Memory Mode = 1
If this is high, the connection memory is in the per-channel control mode
which is per-channel tristate, per-channel message mode or per-channel BER
mode.
Note: For proper
μ
-
law/A-law conversion, the CM_H bits should be set before Bit 15 (UAEN bit) is set to high.
