7. COMMAND
For example, even if the built-in oscillation circuit is not used, execute the "built-in oscillation circuit OFF
command". Perform read status after executing all the five commands above (for the function not to be used,
execute the OFF command).
This command is used to conduct self-check on a specific error mode, but not used to detect all errors. Even
if the result of read status is "normal" because of an influence of excessive external noise, it could have gone
into malfunction mode of some sort that is not detected by this command. It is recommended to refresh the
state regularly instead of relying on the result of read status. Moreover, garbled bit data of display data RAM
may have been caused when an error was detected. So it is also recommended to refresh the data of the display
data RAM.
Since the register P0 level is output from the pin ERR, the operating state can be checked without executing a
command. For ERR output operating conditions and precautions, conform to the above read status command.
(25) Temperature sensor ON/OFF
This command allows specification of the temperature sensor ON/OFF. For more information, see 6.10

Setting the temperature sensor to ON is no problem when the temperature sensor is not use. However,
operating current of the temperature sensor is steadily consumed.
The temperature sensor circuit is controlled independently of the power save command. To reduce current
consumption during power saving, set the temperature sensor to OFF using this command.
(26) Select MLS drive
This command is used for selecting the MLS drive and method of AC drive. It should be selected according
to display quality on actual display patterns.

N-line frame inversion overlap ON / OFF
This function is controlled by parameter P4. It is valid only in "n-line inverted drive ON".
It may cause dark / light stripes on the display due to occur AC drive deflection depend on combination of
number of display lines and number of n-line inverted drive. This function reduces the AC drive defledction
therefore reduce the dark / light stripes.
Dispersion / Non-dispersion drive
This function is controlled by parameter P3. The S1D15722 uses 4 line MLS drive method, and common
