Description (all registers can be written to and read from)
This 8-bit register selects color mode, for instance 8-bit Pseudo
Color, Hi-Color, True Color, or XGA, and DAC power down.
The registers are reset to pseudo color mode on power up.
There are 16 PLL parameter registers accessible as indexed by
Read/Write registers. Parameter registers 0F and 0D-00 are two
bytes long and 0E is one byte long. Register 0E is a control reg-
ister. The bits of this register include clock select and enable
functions, the rest contain PLL frequency parameters. After writ-
ing the start index address in the PLL address register, these reg-
isters can be accessed in successive two (or one) bytes. The
address register auto increments after one (0E) or two bytes to
access the entire register
