a) Is there a partial update or fast update for the SW074AS182 or S2A20CS171?
I was looking at [TCS-P_DevelopersGuide_rF.pdf] but can only see Display Refresh which takes up to 5.3sec (depending on temperature).
I would like to display a Power Fail message on a portion of the display using a supercap to hold sufficient power, but the current*time is quite significant.
If I can update just a portion of the display with a Power Fail message then that could save time and energy.
b) If the driver IC in SW074AS182 or S2A20CS171 doesn't support this, then can I drive these displays directly from a Microchip PIC32 using its LCCG module, and thus have direct control of the display updating?
