The LCD timing generation provides an interrupt that defines the LCD frame timing. This interrupt
can be used to coordinate the writing of the pixel data with the start of a new frame. Writing pixel
data at the frame boundary allows a visually crisp transition of the image. This interrupt can also
be used to synchronize external events to the LCD. For example, the interface to an external seg-
ment driver, such as a Microchip AY0438, can be synchronized for segment data update to the
LCD frame.
A new frame is defined to begin at the leading edge of the COM0 common signal. The interrupt
will be set immediately after the LCD controller completes accessing all pixel data required for a
frame. This will occur at a certain fixed time before the frame boundary as shown in
The LCD controller will begin to access data for the next frame within T
