6.5. Debug LCD Module

A debug LCD module is supplied to be connected to the connector LCD. This should be fitted so that the debug LCD module lies over J1.

Care should be taken to ensure the pins are inserted correctly into LCD. The debug LCD module uses a 4 bit interface to reduce the pin

allocation. No contrast control is provided; this is set by a resistor on the supplied display module. The module supplied with the RSK only

supports 5V operation.

Table 6-4 shows the pin allocation and signal names used on this connector.
