RapidConfigure (RC) is a 25 signal parallel interface that is used to program the OCX160 device. The 25
pins are allocated as follows:
RCA[6:0] = RapidConfigure Address A. RCA are input pins.
RCB[6:0] = RapidConfigure Address B. RCB are input pins.
RCI[3:0] = RapidConfigure Instruction Bits
RCO[4:0] = RapidConfigure Readback. RCO are output pins.
RC_CLK# = RapidConfigure Clock (negative edge clock)
RC_EN# = RapidConfigure Cycle Enable (active low)

Reset the entire crosspoint array to no
connect. All Output Buffers remain
unchanged by this operation.
Connects the input selected by RCB[6:0]
to all output ports and disconnects all
other inputs. The Global Update
(UPDATE#) pin must be held high
during Broadcast mode. Activating the
Global Update pin returns the array to
the previous program condition.
Program an Output Buffer specified by
RCA[6:0].
See Table 5 for RCB[6:0] bit assignment
and buffer functionality.
This is a two-cycle instruction.
Specify the crosspoint connect status at
input location specified by RCA[6:0] to
the output location specified by
RCB[6:0].
