Before entering Power-down mode, Standby mode or ADC Noise Reduction mode with synchro-
nous LCD clock selected, the user have to disable the LCD. Refer to
page
When LCDBL is written to one, the LCD is blanked after completing the current frame. All seg-
ments and common pins are connected to GND, discharging the LCD. Display memory is
preserved. Display blanking should be used before disabling the LCD to avoid DC voltage
across segments, and a slowly fading image.
For LCD with less than 25/40 segment terminals, it is possible to mask some of the unused pins
and use them as ordinary port pins instead. Refer to
pins are automatically configured as port pins.
