FLOE#
OUT
Flash Output Enable.
This pin provides an active low output enable
control (read) to the Flash memory. If the modem is enabled, this is an
active-low output enable (read) of the modem.
FLWE#
OUT
Flash Write Enable.
This pin provides an active low write enable
control to the Flash memory. If the modem is enabled, this is an active
low write-enable to the modem.
CFCS#
OUT
Security ASIC Chip Select.
This pin provides an active low function
enable to enable/disable Flash memory in Combo designs. This signal
is asserted high to enable Flash memory in LAN/modem designs. If
this signal is asserted low, the modem device is enabled, and local bus
signals are defined for modem. This pin is controlled by setting/
clearing the Boot Enable bit in the BootROM BAR. This bit is set
following a PCI reset enabling external Flash.
CFCLK
OUT
Security ASIC Clock.
This pin provides a clock out to a companion
ASIC residing on the local bus. This pin should be left unconnected in
designs that do not utilize a companion ASIC on the Flash interface.
