Functional Description
In the transceiver mode, data present at the HIGH imped-
ance port may be stored in either the A or B register or
both. The select (SAB
n
, SBA
n
) controls can multiplex
stored and real-time. The examples shown below demon-
strate the four fundamental bus-management functions
that can be performed.
The direction control (DIR
n
) determines which bus will
receive data when OE
n
is LOW. In the isolation mode (OE
n
HIGH), A data may be stored in one register and/or B data
may be stored in the other register. When an output func-
tion is disabled, the input function is still enabled and may
be used to store and transmit data. Only one of the two
busses, A or B, may be driven at a time.
