These registers control the Ink Layer/Hardware Cursor FIFO depth in order to sustain
uninterrupted display fetches.
REG[07Eh] determines the FIFO high threshold for the LCD Hardware Cursor/Ink Layer.
REG[08Eh] determines the FIFO high threshold for the CRT/TV Hardware Cursor/Ink
Layer. When this register is set to 00h, the threshold is automatically set in hardware. For
further information, see the 13506 Hardware Functional Specification, document number
X25B-A-001-xx.
