Nonvolatile Write Acknowledge Polling
After a nonvolatile write command sequence (for either the
EEPROM array, the Non Volatile Memory of a DCP (NVM),
or the CONSTAT Register) has been correctly issued
(including the final STOP condition), the X9520 initiates an
internal high voltage write cycle. This cycle typically requires
5 ms. During this time, no further Read or Write commands
can be issued to the device. Write Acknowledge Polling is
used to determine when this high voltage write cycle has
been completed.

FIGURE 5. ACKNOWLEDGE POLLING SEQUENCE
To perform acknowledge polling, the master issues a START
condition followed by a Slave Address Byte. The Slave
Address issued must contain a valid Internal Device
Address. The LSB of the Slave Address (R/W) can be set to
either 1 or 0 in this case. If the device is still busy with the
high voltage cycle then no ACKNOWLEDGE will be
returned. If the device has completed the write operation, an

ARRAY
The X9520 includes three independent resistor arrays.
These arrays respectively contain 63, 99 and 255 discrete
resistive segments that are connected in series. The
physical ends of each array are equivalent to the fixed
terminals of a mechanical potentiometer (R Hx and R Lx
inputs - where x = 0,1,2).
