PIO Writes
PIO writes are used for all LAN9220 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:
A PIO Write cycle begins when both nCS and nWR are asserted. The cycle ends when either or both nCS
and nWR are deasserted. They may be asserted and deasserted in any order. Parameters tcsh and tcsl
must be extended using wait states to meet the tcycle minimum.
