Bias Level Selection Bits. See Table 80.
Description
This bit should be kept cleared for proper operation.
Frame Inversion Mode Enable Bit. If this bit is set, frames are inverted every other frame. If this bit is
cleared, frames are not inverted.
These bits should be kept cleared for proper operation.
Update Finished Flag Bit. This bit is updated by the LCD driver. When set, this bit indicates that the
LCD memory has been updated and a new frame has begun.
Refresh LCD Data Memory Bit. This bit should be set by the user. When set, the LCD driver does not
use the data in the LCD data registers to update the display. The LCD data registers can be updated
by the 8052. When cleared, the LCD driver uses the data in the LCD data registers to update display
at the next frame.
