4.6 LCD Connector
The LCD module is connected to the main circuit board via a 30-conductor flat flex cable (FFC) with 0.5
mm spacing. The main board connector is an FFC, Right Angle Dip, zero insertion force (ZIF), 30 pin
connector (J13).
NOTE
The LCD connector is a ZIF unit. Be sure to release the connector before
trying to connect or disconnect the FFC to the LCD.
4.7 Debug/Development Connectors
4.7.1 ARM JTAG Interface Connector
The MC1322x supports connection to a subset of the defined ARM JTAG connector. The JTAG interface
is a standard 2.54mm/0.1inch spacing, 20-pin debug interface (J1). The 20-pin connector is clearly
separated from the GPIO pin header (J2) and located at the rear side of the module. The 20-pin connector
has Pin 1 marking for correct plug-in of the development cable.
Table shows the device pins that are connected to the associated JTAG header pin outs if the JTAG
connector is used.
