6.6. Debug LCD Module

A LCD module is supplied to be connected to the connector LCD. This should be fitted so that the LCD module lies over J4. Care should be

taken to ensure the pins are inserted correctly into LCD. The 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 Renesas Starter Kit only supports

5V operation.

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