DATASHEET
Note:
A PIO Burst Read cycle begins when both nCS and nRD are asserted. The cycle ends when
either or both nCS and nRD are deasserted. They may be asserted and deasserted in any
order.
6.4
RX Data FIFO Direct PIO Reads
In this mode the upper address inputs are not decoded, and any read of the LAN9117 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 LAN9117. 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
