Key matrix & Key-input data storage ram

The key matrix is made up of 8x 2 arrays as shown below:

K1

K2

Each data entered by each key is stored as follows. They are read by a READ Command, starting from the last

significant bit. When the most significant bit of the data (SG1, b0) has been read, the least significant bit of the

next data (SG8, b7) is read.
