Programming the Monitor Port
The 33rd output port, called the monitor port, is
programmed in the same manner as the other 32
output ports with the exceptions that the LOAD and
Output Address inputs are ignored.
Mode 1 is broadcast operation. In this mode, the
RESETIN signal clears all of the configuration registers
immediately forcing all output ports to be connected to
input port 0. The device will remain in the Mode 1 reset
state as long as the RESETIN input is asserted.
To program the monitor port, apply the desired input
port address to inputs (IADD0:5) and assert the
MONITOR_LD input. Like the other 32 output ports, the
CONFIGURE input is asserted to apply the new
configuration to the switch core.
Reset Programming
The RESETIN is an active high input which sets all of
the switch multiplexers to a defined configuration.
There are three RESET modes available when RESETIN
is used in conjunction with CONFIGURE and IADD5
inputs.
The monitor port is reset to input D0 regardless of the
state of CONFIGURE or IADD5.
Modes 2 and 3 place the device into pass-through
configuration. The mode is controlled by the assertion
of CONFIGURE immediately following the de-assertion
of RESETIN and the state of input IADD5.
Mode 2, or low-order pass-through, is set with the
assertion of CONFIGURE with IADD5 input low. In this
mode, inputs D0 to D31 are configured to outputs O0
to O31 respectively (D0 to O0, D1 to O1,,,D31 to O31).
Mode 3, or high-order pass-through, is set with the
assertion of CONFIGURE with IADD5 input high. In this
mode, inputs D32 to D63 are configured to outputs O0
to O31 respectively (D32 to O0, D33 to O1,,,D63 to
O31).
