Features 01H and 81H are used to enable and clear 8-bit data transfer mode. If the 01H feature
command is issued all data transfers will occur on the low order D7-D0 data bus and the IOCS16#
signal will not be asserted for data register accesses.
Features 55H and BBH are the default features for the ADM; thus, the host does not have to issue this
command with these features unless it is necessary for compatibility reasons.
Features 66H and CCH can be used to enable and disable whether the Power On Reset (POR)
Defaults will be set when a software Reset occurs.
