Display Window Overview and Description

3.5Display 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.
