READ COMMAND
If the R/W bit is set to a logic “high”, then the device
outputs on SDA pin, the DAC register and EEPROM
data. Figure 6-3 shows an example of reading the
register and EEPROM data. The 2nd byte in Figure 6-
3 indicates the current condition of the device
operation. The RDY/BSY bit indicates EEPROM
writing status. The RDY/BSY bit stays low during
EEPROM writng and high when the writing is
completed.
