Description
Phy-Link Data Bus
Phy-Link Control Bus
49.152 MHz clock sourced by PHY
Link Request
Requests link to power up when in a low power mode
Indicates to phy that link is powered and ready
ARM external data bus
ARM external address bus
ARM external chip selects. CS0# is always used for program
ROM.
ARM external output enable. Active when reading data from
external devices including program ROM
Write Enable. Active when writing to external devices
External ARM interrupt
IDE data bus
IDE address bus
IDE chip select. Used to select the Command Block or
Control Block registers.
IDE output enable. Only used when external buffering is
required to drive IDE data bus
IDE interface reset
IDE interface write strobe
IDE interface read strobe
General Purpose Output 1
General Purpose Output 2
General Purpose Output 3
General Purpose Input
Global reset for the OXFW911. Active Low.
Clock output. 49.152 MHz clock output.
‘100’ = NORMAL OPERATION. Other settings are for
foundry test purposes only.
Leave unconnected to use internal Flash, tie low to use only
external device
Supplies power to output buffers in switching (AC) state
Power supply. Supplies power to core logic, input buffers
and output buffers in steady state
