This function delays updating the grayscale (GS) and dot correction (DC) data until the end of one entire display period. If both DC data and GS data are written by the end of an entire display period, the input DC data are held in the control data latch and the GS data are held in the common shift register. Both DC and GS data are copied to the 336-bit DC data latch and 768-bit GS data latch at the end of an entire display period. The data latches are used for the next display period. GS data are directly copied from the common shift register to the GS data latch. Therefore, GS data must be written after the DC data are written. Furthermore, the GS data in the common shift resistor must not be changed until all data are copied to the GS data latch. Figure 8-11 and Figure 8-12 show timing diagrams for this function.
