SCAN CODE TABLE
Scan codes are a function of the physical position of the
keyboard keys. The following table shows the 8- bit
scan code, the hexadecimal code, and the key position
for the keyboards. The
*
(asterisk) in scan code position
o
indicates that the key is a make/break key with a bit
setting of either 0 or 1. When a make/break key is
pressed, bit 0 of the code is a O. When a make/break
key is released, bit 0 of the code is a 1. When the US
and the Katakana scan codes are different, the Katakana
code is listed below the US code for that key position.
