A random read operation is shown in Figure 21. This operation
changes the address counter to the specified memory address by
performing a dummy write and then performing a read
operation beginning at the new address counter location.
EEPROM Write Protection
Setting the WP pin to logic low protects the EEPROM memory
from future write operations. In this mode, EEPROM and
RDAC register readings operate normally.
