Command 2 when used in conjunction with the Carriage
Return Code (FEH) determines the size of characters to be
displayed on the next line, sets the spacing between lines
of characters and enables/disables the display.
The character size is also a function of the TV scanning
standard being used and f

; this is explained in
Chapter 12.

Command 2 when used in conjunction with the Space
Code (FFH) selects the background colour of characters in
Box shadowing or North West shadowing modes and also
controls the Active Character Monitor pin. The ACM pin will
remain active until a Space Code is received that resets
the ACM bit to logic 0. The ACM timing diagram is shown
in Fig.10.
