addresses. This is due to the use of the 8-bit RS8223 interface mode which adds a
single clock delay in presenting the read data on the data bus during reads to odd
addresses only. This is not documented in the RS8223 data sheet. Setting the
PHY_WAIT control to one provides for this requirement. Note that all accesses
take an additional cycle with this control set, not just reads to odd addresses.
16.4 Absolute Maximum Ratings
Stresses above those listed as absolute maximum ratings
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those indicated in
other sections of this document is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability. This device
should be handled as an ESD-sensitive device. Voltage on any signal pin
exceeding 5.5 V can induce destructive latchup.
