D5

D3
D2
D1
D0
The key number indicated by D5:D0 is a key event. D7
is always for a key press of key 62 and key 63. When
D7 is 0, the key read is the last data in the FIFO. When
D7 is 1, there is more data in the FIFO. When D6 is 1,
key data read from FIFO is a key release. When D6 is
0, key data read from FIFO is a key press.
