For 4 gray-scale display, 2-bit of RAM is required for each pixel and 4 bit for 16 gray-scale display, 1-bit
for black and white display. For different LCD configuration, the LCD display RAM is arranged
differently. The following figure shows one byte of RAM in different LCD configurations:

The 16 Gray Scale register GRAY0 ~ GRAYF is the mapping register between the levels selected in
RAM and the real gray scale. In other words, if the content of GRAY0 is 0x03, when value of a certain
pixel is 0, the displayed effect will correspond to actual gray level 3. The 16 gray scale display use all 16
registers GRAY0 ~ GRAYF to select among 32 available gray levels to correspond to level 0 ~ 15, while
4 gray scale display utilizes registers GRAY0 ~ GRAY3 to select among 32 gray levels to correspond to
level 0 ~ 3. Thus user can pick the gray levels which give the best and most linear effect.
16 Gray Scale registers share a common register address GRAY16. When writing is made to the register,
it will step down to next register in order. The writing sequence can be reset by clearing bit 5 of LCDC
register.
