Figure 9–3 Module Display Control Register

MOD_DISP_REG :
Brightness Control
Display Character
The display character is stored in bits <6:0>. The most significant bit (bit <7>)
can be set to increase the brightness of the display.
Figure 9–4 shows the character set of the display. The numbers along the left-
hand edge are the most-significant hexadecimal digit of the character number,
while the least-significant is along the top. For example, the character ''W'' is
displayed by writing a value of 0x57 to the display register. A value of 0xD7
displays ''W'' with full brightness.
After a system reset, the display defaults to character 0x7F ('':::'') at full
brightness. During a system reset, all dots in the matrix are lit.
