SML2108
PRELIMINARY
SUMMIT MICROELECTRONICS, Inc.
In the write mode the SML2108 receives eight bits of data,
then generates an Acknowledge signal. It will continue to
generate ACKs until a Stop condition is generated by the
Master. See Figure 13.
Random Address Read
Random address Read operations allow the Master to
access any memory location in a random fashion. This
operation involves a two-step process. First, the master
issues a write command which includes the start condition
and the Slave address field (with the R/W bit set to Write)
followed by the address of the word it is to read. This
procedure sets the internal address counter of the
SML2108 to the desired address. After the word address
acknowledge is received by the Master, it immediately
reissues a start condition followed by another Slave ad-
dress field with the R/W bit set to Read. The SML2108 will
respond with an Acknowledge and then transmit the 8 data
bits stored at the addressed location. At this point, the
Master does not acknowledge the transmission, but does
generate a Stop condition. The SML2108 discontinues
data transmission.

Sequential READ
Sequential Reads can be initiated as either a current
address Read or a random access Read. The first word
is transmitted as with the other byte read modes (current
address byte Read or random address byte Read). How-
ever, the Master now responds with an Acknowledge,
indicating that it requires additional data. The SML2108
continues to output data for each Acknowledge received.
The Master terminates the sequential Read operation by
not responding with an Acknowledge, and issues a Stop
condition. During a sequential read operation the internal
address counter is automatically incremented with each
Acknowledge signal. For Read operations all address bits
are incremented, allowing the entire array to be read using
a single Read command. After a count of the last memory
address the address counter will
‘
roll-over
’
and the
memory will continue to output data.
The protocol for reading and writing to the registers and
the lookup table are illustrated in Figures 14 through 24.
