4.7 User Interface
4.7.1 Keypad
The keypad interface consists of a 5 X 6 matrix pattern. The 5-KEYSENSE/[4:0] pins are used to
connect a matrix keypad to the module. The KEYSENSE/ pins are active low.
The 6-KEYPAD pins are necessary to construct the other side of the matrix. These KEYPAD pins
must be active high in order for the keypad matrix to work properly. The general keypad matrix is shown
below:
