Example 1: Bitmap encoding
To clarify this, lets try a simple example. X’s represent black dots in the fi nal
printout. The pattern shown is 22 bits wide and 28 rows high.
NOTE!
• The bit order in each byte. Note also word fi ll to nearest word (16 bit).
• To the right is a hex representation of the pattern, as it would appear
in a memory dump.
• To get the pattern to appear as printed on this page with direction one, the
last row (row 27) should have the lowest address.
