1.5 Connectors and User Components
1.5.1 Keypad
The Keypad port provides MPC566 I/O connections for a passive 16 key 4x4 matrix keypad
(Axiom HC-KP). The port is applied as 4 column drivers and 4 row inputs. The MPC566
QADC_B Ports PQA[4:7] are column outputs and PQB[4:7] are row inputs. The row inputs have
10K ohm pull-down resistance applied to idle the row inputs low. A simple keypad scan will
enable each column output high one at a time and test the input rows for a high input. Column and
row position can then determine the value of the key pressed. Sample software for driving the
Keypad Port is provided on the MPC5xx support CD.
1.5.2 LCD Port
The LCD Port provides a versatile connector to attach 80 or 160 character display modules and
some graphics display modules with embedded controllers. Most LCD modules operate very

This optional signal is not available on the MPC56x devices.
This signal is needed only if control of EPEE or B0EPEE is
required by the Nexus tool.
This optional signal is defined for use by tool vendors and has no
defined connection to the MPC56x device.
This signal depends on the following system requirements:
KAPWR (Y26), VDDSRAM1 (E3), VDDSRAM2 (D2), or
VDDSRAM3 (G4). This pin should be connected to the standby
supply used in a particular system.
