10.3.4 Gray Scale Register
GRAYSCALE
The GRAYSCALE command selects the gray scale depth, in bits-per-pixel (bpp), when
indirect addressing is used. The values from REG[20h] are passed as parameters when the
GRAYSCALE command is issued. For further information on the GRAYSCALE
command, see Section 11.1.12, “GRAYSCALE” on page 78.
bits 1-0
Bit-Per-Pixel Select bits [1:0]
These bits select the bit-per-pixel mode as follows.
Note
The horizontal character size (REG[01h] bits 3-0) must be set to 7h and the Horizontal
Pixel Scroll bits (REG[1Bh] bits 2-0) must be set to 0.
