KEY CODES
The key codes are given in Table 1.1. There is a separate code for the key when it is pushed
versus when it is released.
NOTE: The key release codes are identical to the key pressed codes
except that the most significant bit in the code is a “1”. Therefore,
the following formula holds true:
Code for Key Release = Code for Key Press + 0x80 (hex)
