23.5.1.1 Signals used for single panel STN displays
23.5.1 Signal usage
More than 4 bpp for monochrome panels can be programmed, but using these modes has
no benefit because the maximum number of gray scales supported on the display is 15.
The largest configuration for the LCD controller uses 31 pins. There are many variants
using as few as 10 pins for a monochrome STN panel. Pins are allocated in groups based
on the selected configuration. All LCD functions are shared with other chip functions. In

The signals that are used for various display types are identified in the following sections.
The signals used for single panel STN displays are shown in
upper panel data.
