Connection Memory, Read/Write
-- Address: 80H-FFH
* 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.

Description
Per Channel Loop Back. When 1, the STi n Channel m data comes from the STo n Channel m. For
proper per channel feedback operations, set the delay Offset register bits OFn [2:0] to zero for the
streams which are in the feed back 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 output drivers on a per-channel basis. When 1, the output
driver functions normally. When 0, the output driver is in high-impedance state.
10-7*
SAB3-0
Source Stream Address Bits. The binary value is the number of the data stream for the source of
the connection.
6-0*
CAB6-0
Source Channel Address Bits. The binary value is the number of the channel for the source of the
connection.
