Auto recall function (ARF)
After the power supply is turned on, the data for address 00h is automatically loaded and the wiper position set. At
this point, if the data for address 00h is larger than 64h, the wiper position is set to 32h. Since the wiper position is
set using seven bits, the eighth bit may be set to any value. This function is carried out 10ms after the power supply
is turned on, and subsequently the IC enters the standby state.
