Fine adjustment of the input offset voltage can be done in order to
suppress the error voltage of the output based on the input voltage.

Operation notes
(1) When turning the power supply on and off
1) When turning the power supply on and off, CS should be set to HIGH ( = V
CC
).
2) When CS is LOW, the BU9831 is active, meaning that input can be received. If the power supply is turned on in
this state, noise and other factors can cause malfunctioning and erroneous writing. To prevent this, when turning the
power supply on, make sure that CS is HIGH ( = V
CC
).
(Example of proper operation) The CS pin is pulled up to V
CC
.
After turning the power supply off, wait at least 10ms before turning it on again.
If the power supply is turned on without observing this condition, please be aware that there may be times
when the circuits in the IC are not reset.
(Example of incorrect operation) The CS pin is LOW when the power supply is turned on or off.
In this case, CS is normally LOW, and the EEPROM may cause malfunctioning or erroneous writing
because of noise.
Be aware that the case shown in this example may occur even if the CS input is HIGH-Z.
