Timing Diagram
Figure 4. Timing diagram when 6bits are correction terms and 8bits are image terms
When 6 bits are correction terms and 8 bits are image terms (as shown in Fig 4), users
must set the controller signals according to below sequences:
(1) Set SELBK=L (Bank 0) and begin shift in 6 bits correction data
(2) Set LAT_B=H to update the correction data after all correction data are in place
(3) Set SELBK=H (Bank 1) and begin shift in 8 bits image data
(4) Set LAT_B=H to update image data after 8 bit image are all in place. DM163 will utilize
the 8 bits image data to determine the grayscale of each channel
(5) Repeat steps (3) and (4)
