When key_code return is enabled, and AT503-4K does not display anything both on
illuminant buttons and LED display, the these 4 buttons can be function keys. But before
this function is enabled, it needs to send sub-command = 01H to clear the buffers
firstly, otherwise it will conflict with “re-display function”.
When push it, it will return message back with sub-command = 64H and Data 0 = 05H and
Data 1 to notify the button index
Data 1 = 00H -> 1
