(R/W=0) is placed on the bus and indicates to the addressed device that word address “An”
will follow and is to be written to the on-chip address pointer. The data word to be written to
the memory is strobed in next and the internal address pointer is incremented to the next
address location on the reception of an acknowledge clock. The M41T6x slave receiver will
send an acknowledge clock to the master transmitter after it has received the slave address
