LCD Display FIFO Low Threshold Bits [5:0]
When this register is set to 00h, the threshold is automatically set in hardware. If it
becomes necessary to adjust REG[04Ah] from its default value, then the following
formula must be maintained:
REG[04Bh] > REG[04Ah] and REG[04Bh] ≤ 3Ch

CRT/TV Horizontal Display Width Bits [6:0]
These bits specify the CRT/TV horizontal display width, in 8 pixel resolution.
Horizontal display width in number of pixels = ((ContentsOfThisRegister)+ 1) × 8

Period Bit 5 Period Bit 4
CRT/TV Horizontal Non-Display Period Bits [5:0]
These bits specify the CRT/TV horizontal non-display period width in 8 pixel resolution.
Horizontal non-display period width in number of pixels =
((ContentsOfThisRegister) + 1) × 8 for CRT mode
(ContentsOfThisRegister) × 8 + 6 for TV mode with NTSC output
(ContentsOfThisRegister) × 8 + 7 for TV mode with PAL output
For CRT mode, the recommended minimum value which should be programmed into
this register is 3 (32 pixels).
