LTDC active width configuration register
| AAH | accumulated active height (in units of horizontal scan line) These bits define the accumulated height which includes the vertical synchronization, vertical back porch and the active height lines minus 1. The active height is the number of active lines in the panel. Refer to device datasheet for maximum active height supported following maximum pixel clock. |
| AAW | accumulated active width (in units of pixel clock period) These bits define the accumulated active width which includes the horizontal synchronization, horizontal back porch and active pixels minus 1. The active width is the number of pixels in active display area of the panel scan line. Refer to device datasheet for maximum active width supported following maximum pixel clock. |
