Description
15-14
TM1-0
Mode Select Bits.
TM1 TM0
Mode Selection
0 0 Variable Throughput Delay mode (Note 1)
1 0 Constant Throughput Delay mode (Note 2)
0 1 Message mode; 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.
1 1 Bit Error Test mode; the pseudo random test pattern will be
output on the output channel and stream associated with this
location.
13
OE
Output Enable.
This bit enables the drivers of STo pins on a per-channel
basis. When 1, the STo output driver functions normally. When 0, the STo
output driver is in a high-impedance state.
12-8
SAB4-0
Source Stream Address Bits.
The binary value is the number of the data
stream for the source of the connection.
7-0
CAB7-0
Source Channel Address Bits.
The binary value is the number of the channel
for the source of the connection. When the message mode is enabled, these
entire 8 bits are output on the output channel and stream associated with this
location.
Note 1:
The Variable delay is only available for odd number output streams but not for the even number output streams. Avoid
programming the TM0 and TM1 bits to zero in the connection memory when the destination output streams are STo0, 2, 4,
... , 28 and 30.
The constant delay mode is available for all output streams.
