the Device Type Identifier 1010111 or 1010010). Imme-
diately after an operation to a DCP or CR Register is
performed, only a “Random EEPROM Read” is avail-
able. Immediately following a “Random EEPROM
Read” , a “Current EEPROM Address Read” or
“Sequential EEPROM Read” is once again available
(assuming that no access to a DCP or CR Register
occur in the interim).
Random EEPROM Read
Random read operation allows the master to access
any memory location in the array. Prior to issuing the
Slave Address Byte with the R/W bit set to one, the
master must first perform a “dummy” write operation.
The master issues the START condition and the Slave
Address Byte, receives an ACKNOWLEDGE, then
issues an Address Byte. This “dummy” Write operation
sets the address pointer to the address from which to
begin the random EEPROM read operation.
After the X4023x acknowledges the receipt of the
Address Byte, the master immediately issues another
START condition and the Slave Address Byte with the
R/W bit set to one. This is followed by an ACKNOWL-
EDGE from the X4023x and then by the eight bit word.
The master terminates the read operation by not
responding with an ACKNOWLEDGE and instead issu-
ing a STOP condition (Refer to Figure 15).
A similar operation called “Set Current Address” also
exists. This operation is performed if a STOP is issued
instead of the second START shown in Figure 15. In
this case, the device sets the address pointer to that of
the Address Byte, and then goes into standby mode
after the STOP bit. All bus activity will be ignored until
another START is detected.
