After the device address byte, a command byte must
be sent by the master to indicate the type of operation
to be performed. The code for each instruction is listed
in Table 4-1.
TABLE 4-1:
4.1
The Read command allows the master to access any
memory location in a random manner. After the
instruction has been sent to the slave, the two bytes of
the Word Address are transmitted, with an Acknowl-
edge sequence being performed after each byte. Then,
the slave sends the first data byte to the master. If more
data is to be read, the master sends a MAK, indicating

that the slave should output the next data byte. This
continues until the master sends a NoMAK, which ends
the operation.
To provide sequential reads in this manner, the 11XX
contains an internal Address Pointer which is incre-
mented by one after the transmission of each byte. This
Address Pointer allows the entire memory contents to
be serially read during one operation. When the highest
address is reached, the Address Pointer rolls over to
address ‘0x000’ if the master chooses to continue the
operation by providing a MAK.
