Display data registers
The display data registers consists of a group of 32 derivative registers located at addresses 20H to 3FH inclusive
(see Table 7). At power-up the contents of the display data registers are undefined.
The format of each display data register is shown in Table 8, and their functions described in Table 9.

Display control registers
The display control registers consists of a group of 6 derivative registers located at addresses 40H to 45H inclusive
(see Table 10). Each register may be read from or written to. After a reset operation the contents of the display control
registers are zero.

Colour code
. The state of these two bits enable individual characters to be displayed in
one of four colours. See Tables 24, 25 and 26.
Character code
.
The character set is stored in ROM and consists of 64 different characters.
The selection of each character is dependent on the state of the 6 bits, MD0 to MD5.
