M41T256Y
WRITE Mode
In this mode the master transmitter transmits to
the M41T256Y slave receiver. Bus protocol is
shown in Figure 13., page 11. Following the
START condition and slave address, a logic '0' (R/
W=0) is placed on the bus and indicates to the ad-
dressed device that byte addresses A(0) and A(1)
will follow and is to be written to the on-chip ad-
dress pointer (MSB of address byte A(0) is a
“Don’t care”).
The data byte 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 bit.
The M41T256Y slave receiver will send an ac-
knowledge bit to the master transmitter after it has
received
the
slave
address
(see
10., page 9) and again after it has received each
address byte.
