Ink/Cursor Registers
bits 7–6
Ink/Cursor Control Bits [1:0]
These bits select the operating mode of the Ink/Cursor circuitry. See table below.
bits 3–0
Ink/Cursor FIFO Threshold Bits [3:0]
These bits specify the Ink/Cursor FIFO depth required to sustain uninterrupted display
fetches. When these bits are all 0, the Ink/Cursor FIFO depth is calculated automatically.
REG[2Bh] bit 7
Reserved
This bit must be set to 0.
REG[2Ah] bits 7–0
Cursor Y Position Bits [9:0]
REG[2Bh] bits 1–0
In Cursor mode, this 10-bit register is used to program the vertical pixel
position of the Cursor’s top left pixel.
This register must be set to 0 in Ink mode.
Note:
The Cursor X Position register must be set during VNDP (vertical non-display period).
Check the VNDP status bit (REG[0Ah] bit 7) to determine if you are in VNDP, then update
the register.
