WRITE mode

In this mode the master transmitter transmits to the M41TC8025 slave receiver. Bus

protocol is shown in Figure 9 on page 13. Following the START condition and slave

address, a logic '0' (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

M41TC8025 slave receiver will send an acknowledge clock to the master transmitter after it

has received the slave address (see Table 3 on page 11) and again after it has received the

word address and each data byte.
