WSR, WSG, WSB - Define the color of shadowing on windows. The initial value is (0, 0, 0) after power up.
CSR, CSG, CSB - Define the color of bordering or shadowing on characters. The initial value is (0, 0, 0) after
CFONT - Enable 16 multi-color fonts.
WW41, WW40 - Determines the shadow width of the window 4 when WSHD bit of th window 4 is enabled.

2. It is necessary to wait for the PLL to become stable while (i) the HORR register is changed; (ii) the (VCO1, VCO0)
3. When PLL is unstable, don't write data in any address except Column 15,17,18 of Row 15. If data is written in any
