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 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 procedures are duplicated, the Dout output
is the EEPROM content. 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 20) is set to low (“0”) to
access the Enhancement mode.
