During the programming of the device the temperature must be between 10°C and 40°C.
The capacitor on VREG is mandatory.
The capacitor on VMULT is optional. The capacitor has to be present if the multiplier is enabled. The
multiplier has to be enabled if VBAT<3.0V.
The capacitor may be omitted when VREG is connected to VBAT.
The voltage reference for the LCD drivers starts operating at 1.5 V.
The capacitor on VMULT is optional. The capacitor has to be present if the multiplier is enabled. The
multiplier has to be enabled if VBAT<3.0V.
