A similar operation called “Set Current Address” where
the device will perform this operation if a stop is issued
instead of the second start shown in Figure 15. The
device will go into standby mode after the stop and all
bus activity will be ignored until a start is detected. This
operation loads the new address into the address
counter. The next Current Address Read operation will
read from the newly loaded address. This operation
could be useful if the master knows the next address it
needs to read, but is not ready for the data.
Sequential Read
Sequential reads can be initiated as either a current
address read or random address read. The first Data
Byte is transmitted as with the other modes; however,
the master now responds with an acknowledge, indicat-
ing it requires additional data. The device continues to
output data for each acknowledge received. The master
terminates the read operation by not responding with an
acknowledge and then issuing a stop condition.
The data output is sequential, with the data from
address n followed by the data from address n + 1. The
address counter for read operations increments through
all page and column addresses, allowing the entire
memory contents to be serially read during one opera-
tion. At the end of the address space the counter “rolls
over” to address 0000h and the device continues to out-
put data for each acknowledge received. See Figure 17
for the acknowledge and data transfer sequence.

Slave Address Byte
Following a start condition, the master must output a
Slave Address Byte. This byte consists of several parts:
– a device type identifier that is always ‘101x’. Where
x=0 is for Array, x=1 is for Control Register or Fault
Detection Register.
– next two bits are ‘0’.
– next bit that becomes the MSB of the address.
