LCD Charge Pump Usage for PIC16LF19197
I am trying to drive a segmented LCD display with the PIC16LF19197 microcontroller. I am new to using microcontrollers, and I've been trying to figure out how the LCD charge pump works for the controllers in this family.
I am powering the board with two AAA batteries (1.5V each, 3V total). The controller is using one Common and a pin per segment (static bias mode).
If I configure the controller in the M0 configuration, does that simply raise the LCDBIAS3 to an independent voltage (up to 3.6V), or does it raise each SEG pin to the 3.6V value?
Ideally this would allow the charge pump to compensate for a partially discharged battery which would give the device a longer life.
(Is there anything that I need to make my question clearer / more specific?)
EDIT: Changed the Micro to actually be the right part....
