Save This Code
  ; before the below statement acc will be having the 
  ; value of PORT 1
  anl   a, #0f0h ; here columns are made low and only
                 ; rows are scanned
  cjne  a, #0e0h, ROW_SCAN_2
  sjmp  ROW_1
You make all columns low, then you test for a row.

What this will tell you is that a key in row 1 and any column is pressed. I do not know what that information is good for.
