LCD BIST

LCD BIST (Built-In Self Test) helps you determine if a display problem is

caused by the LCD or some other part. The test may displays different colors

and text on the screen and if you do not notice the problem during the test

then the issue lies outside of the LCD.

NOTE:

Peripherals may have diagnostics specific to them. For more

information, see the documentation of the peripheral.
