3.5 Display Window Overview and Description
The display window has two separate areas (see Figure 3–2): the PC
memory display (left half of screen) and the reverse assembled code (right half
of screen).
The programmer displays the PC memory in a hexadecimal format. The
memory address occupies the left-most column of each line, followed by eight
bytes of PC memory contents. Next on the display line are eight characters that
represent the PC memory contents as ASCII values. Nonprintable ASCII char-
acters are represented by the . character.
The address range for the PC memory is from 0000h to FFFFh. Access to the
PC memory out of this range is not allowed. The programmer maintains the
array as a circular buffer so that any scrolling that exceeds the limits is wrapped
around.
The reverse-assembled code window contains the disassembled code from
the PC memory.
