Write mode
In this mode the master transmitter transmits to the M41T11 slave receiver. Bus protocol is

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
memory location within the RAM on the reception of an acknowledge clock. The M41T11
slave receiver will send an acknowledge clock to the master transmitter after it has received
the slave address and again after it has received the word address and each data byte.
