KEY MATRIX & KEY INPUT DATA STOREGE RAM
Key Matrix consists of 10 x 2 arrays as shown below:
Each data entered by each key (or any combination of keys) is stored as follows and read
by a READ Command, starting from the last significant bit. When the most significant bit of
the data (b0) has been read, the least significant bit of the next data (b7) is read.
Note: b2, b5, b6 and b7 do not care.
