8.3.6 Display Timing Strobe Tag Register (LBR_WPTR_L) —FF80:05 (FF85)
This register defines how many pixels have been written into the line buffers, so that the display timing will be
active to synchronize the capture and display timings.

Description
Lower 8 bits of write pointer (LBR_WPTR[7:0])
8.3.7 Display Timing Strobe Tag Register (LBR_WPTR_H) —FF80:06 (FF86)
This register defines how many pixels have been written into the line buffers, so that the display timing will be
active to synchronize the capture and display timings. This register will be concatenated with LBR_WPTR_L
register to be a completed tag pointer.

Description
Full and Empty Reference Tag (Empty_Full_Tag[3:0])
This register defines when the number of slots is empty, and when the
Line Buffer is in Full status. When the number of slots are filled, the Line
Buffers is in Empty status.
