FIFO_SEL
nCS, nRD
A[2:1]
Data Bus
In this mode the upper address inputs are not decoded, and any read of the LAN9220 will read the
RX Data FIFO. This mode is enabled when FIFO_SEL is driven high during a read access. This is
normally accomplished by connecting the FIFO_SEL signal to high-order address line. This mode is
useful when the host processor must increment its address when accessing the LAN9220. Timing is
identical to a PIO read, and the FIFO_SEL signal has the same timing characteristics as the address
lines.
Note that address lines A[2:1] are still used, and address bits A[7:3] are ignored.
Note: The “Data Bus” width is 16 bits.
Note 6.4
Note: An RX Data FIFO Direct PIO Read cycle begins when both nCS and nRD are asserted. The
