Output
Readback (using RCO[4:0]) the status of
the output buffer specified in Cycle 1 by
RCA[6:0], the output buffer specified in
Cycle 1 by RCO[4:0] and the crosspoint
connect status.
See Table 4 for RCO[4:0] readback pin
assignment.
Program the Global Update function
without the use of the UPDATE# pin.
Disconnect the crosspoint cells of the
output row location specified by
RCA[6:0].
Disconnect the crosspoint cell at the
output location specified by RCA[6:0] to
the input location specified by RCB[6:0].
All other connections from the source
input address or to the same output
address remain the same as before.
Connect the crosspoint cell at the output
location specified by RCA[6:0] to the
input location specified by RCB[6:0].
All other connections from the same
input address or to the same output
address are set to no connect (NC).
Connect the crosspoint cell at the output
location specified by RCA[6:0] to the
input location specified by RCB[6:0].
All other connections to the same output
address are set to no connect while all
other connections from the same input
address remain the same as before.
Reset the switch matrix to no connects
