PIO writes are used for all LAN9217 write cycles. PIO writes can be performed using Chip Select (nCS)
or Write Enable (nWR). Either or both of these control signals must go high between cycles for the
period specified.
Note: The “Data Bus” width is 16 bits.
Note: A PIO Write cycle begins when both nCS and nWR are asserted. The cycle ends when either
