configuration is loaded into the PROGRAM register by
asserting the LOAD input high and is latched when
LOAD is de-asserted.
Multicast Program Mode
Multicast programming allows any combination of
output ports to be configured to a single input port in a
single LOAD cycle.
Sequential Program Mode
Sequential programming allows for a single input to
output port assignment per LOAD cycle. Any number
of port assignments can be made with repeated LOAD
cycles prior to assertion of CONFIGURE.
User defined input port assignment
(MODE0=1, MODE1=0)
User defined input port assignment Multicast
programming uses input addresses IADD(0:5) and
output addresses OADD(0:33).
User defined input port assignment
(MODE0=0, MODE1=0)
User defined input port assignment Sequential
programming uses the address inputs IADD(0:5) and
the lower 6 bits of OADD(0:33).
To program, apply the desired output port address to
the address inputs OADD(0:5) and the desired input
port address to the address inputs IADD(0:5). The
input address defines which input port connects to the
selected output port. The new configuration is loaded
into the PROGRAM register by asserting the LOAD
input high and is latched when LOAD is de-asserted.
Default input port assignment (MODE0=0, MODE1=1)
Default input port assignment Sequential programming
uses the same lower 6 bits of OADD(0:33) and ignores
the IADD(0:5) inputs.
To program, apply the desired input port address to
IADD(0:5) and the OADD(0:33) bits which correspond
to the desired output ports. For example, to program
input 1 to output ports 1, 2 and 5; apply "000001" to
IADD(0:5) and apply "00..0100110" to OADD(0:33). The
new configuration is loaded into the program latches
by asserting the LOAD signal high and is latched when
LOAD is de-asserted. This process is continued for
each set of outputs to be programmed to a unique
input. Data is then transferred to the CONFIGURATION
latches upon assertion of CONFIGURE input.
Default input port assignment (MODE0=1, MODE1=1)
Default input port assignment Multicast programming
uses the OADD(0:33) inputs and ignores the IADD(05)
inputs. Apply the desired output ports to be configured
to inputs OADD(0:33). Upon assertion of LOAD, each
output port selected will be programed to its
corresponding input port.
To program, apply the desired output port address to
the address inputs OADD(0:5). The default
