Zarlink Semiconductor Inc.
Table 13 - Connection Memory Bits
Table 14 - CAB Bits Programming for Different Data Rates
Bit
Name
Description
15
LPBK
Per Channel Loopback.
This bit should be use for diagnostic purpose only.
Set this bit to zero for normal operation. When loopback bit is set for all
memory location, the STi
n
channel
m
data comes from STo
n
channel
m
. For
proper per channel loopback operations, set the delay offset register bits
OFn[2:0] to zero for the streams which are in the loopback mode.
14
V/C
Variable /Constant Throughput Delay.
This bit is used to select between
the variable (low) and the constant delay (high) modes on a per-channel
basis.
13
MC
Message Channel.
When 1, the contents of the connection memory are
output on the corresponding output channel and stream. Only the lower byte
(bit 7 - bit 0) will be output to the ST-BUS output pins. When 0, the contents of
the connection memory are the data memory address of the switched input
channel and stream.
12
CSTo
Control ST-BUS output.
This bit is output on the CSTo pin one channel
early. The CSTo bit for stream 0 is output first.
11
OE
Output Enable.
This bit enables the ST-BUS output drivers on a per-channel
basis.
When 1, the output driver functions normally. When 0, the output driver is in a
high-impedance state.
10 - 8,
7
(Note 1)
SAB3-0
Source Stream Address Bits.
The binary value is the number of the data
stream for the source of the connection.
6 - 0
(Note 1)
CAB6-0
Source Channel Address Bits.
The binary value is the number of the
channel for the source of the connection.
Note 1: If bit 13 (MC) of the corresponding connection memory location is 1 (device in message mode), then these entire 8 bits
(SAB0, CAB6 - CAB0) are output on the output channel and stream associated with this location.
Data Rate
CAB Bits Used to Determine the Source Channel of the Connection
2.048 Mb/s
CAB4 to CAB0 (32 channel/input stream)
4.096 Mb/s
CAB5 to CAB0 (64 channel/input stream)
8.192 Mb/s
CAB6 to CAB0 (128 channel/input stream)
