... After the receipt of each data word, bits A1-A0 of the internal address register are incremented, the high order bits remaining unchanged (A7-A2 for M93S66, M93S56; A5-A2 for M93S46). Users must take care, in the software, to ensure that the last word address has the same upper order ad- dress bits as the initial address transmitted to avoid address roll-over ...
