Figure 3: Key Matrix And Key-input Data Storage Ram
The key matrix is of 6 x 4 configuration, as shown below
The data of each key are stored as illustrated below, and are read by the appropriate read command,
starting from the least significant bit
LED PORT
Data are written to the LED port by a write command, starting from the least significant bit of the port.
When a bit of this port is 0, the corresponding LED lights; when the bit is 1, the LED goes off. The data of
bits 5 through 8 are ignored.
