Figure 8. Details of EE register contents loaded from EEPROM and then shifted out Serially through
Dout pin - The procedure is performed twice.
In Figure 8, the first step is to program
Enhancement Register to set Bit 1 high (“1”) to
access EE Register Output Bit Function.
Subsequent action, which includes 19 Clock
pulses, allows the existing EE Register contents to
be shifted out the Dout pin and the EEPROM
contents are loaded to the EE Register. Since the
initial data existing in the EE Register could be
anything, the data must be flushed out before

clocking the contents of the EEPROM register out.
After the same procedure is duplicated, the Dout
output is the EEPROM contents. Note that only
19 Clock pulses are enough for the 20-bit EE
Register because the first bit data is already
present at Dout pin. Also ENH/ (Pin 3 in TSSOP
or Pin 20 in QFN) is set to low (“0”) to access the
Enhancement mode.
