11.10 LCD DMA Channel Current Address Register
This read-only register allows the processor to read the current value of the LCD DMA channel
current address register. This is not something that would normally be done, but it allows
additional test observability. Its value cannot be expected to be exact, it could change at an
moment. However, its contents can be read to determine the approximate line that the LCD
controller is currently displaying and driving out to the display
