Bi-directional data port.
Note that Pull-down’s are disabled in
32 bit mode.
Bi-directional data port.
7-bit Address Port. Used to select
Internal CSR’s and TX and RX FIFOs.
Active low strobe to indicate a read
cycle.
Active low strobe to indicate a write
cycle. This signal, qualified with nCS, is
also used to wakeup the LAN9116
when it is in a reduced power state.
Active low signal used to qualify read
and write operations. This signal
qualified with nWR is also used to
wakeup the LAN9116 when it is in a
reduced power state.
Programmable Interrupt request.
Programmable polarity, source and
buffer types.
When driven high all accesses to the
LAN9116 are to the RX or TX Data
FIFOs. In this mode, the A[7:3] upper
address inputs are ignored.
