I am confused by what is actually sent and returned? Is it the AD value is it the Dirty value? How do the two map to each other?

There are two formats for reading data from the host. One is dirty data, which ranges from 0 to 255, and the other is AD data, which ranges from 0 to 4095. For example, if the AD data is 0X64, which is equivalent to 100 in decimal, it needs to be mapped to the range of 0 to 255. The calculation would be 255 * 100 / 4095 = 6, so the dirty data would be 6. The corresponding voltage is calculated as 5V / 255 * 6 = 0.1V.
