4.2.1.3 Connector 3 and 4
The pinout diagram for J4 looks exactly like the one for J3. The difference is that J4 is made up of one-
transistor cells and J3 is made up of two-transistor cells. This difference means that, for example, the pins
on J4 can be configured for the 100 mA sinking driver or the 100 ohm line driver, but not the 1 A sinking
driver or either of the sourcing drivers available on J1, J2, or J3. Also the 3.45 V power supply is not avail-
able on J4.

4.2.1.4 Connector 5
If the keypad option is selected, it will populate pins on J5. The number of pins depends on the number of
rows and columns chosen. For a 2x3 keypad, six pins are used. For a 4x4 keypad, all eight configurable
pins are used.
