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
LAN9215i 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 LAN9215i when it is in a reduced power
state.
Programmable Interrupt request. Programmable
polarity, source and buffer types.
When driven high all accesses to the LAN9215i are to
the RX or TX Data FIFOs. In this mode, the A[7:3]
upper address inputs are ignored.
