When the LSB is read [A(0) = logic 0], the host interface will read an Hword on the
address location A(22:1). The LSB byte is set on the output bus and the read MSB
byte is stored internally. When a read action is now started whereby the MSB byte is
selected to read [A(0) = logic 1] the stored byte is available on the output independent
on the other address bits A(22:1).
