The SCI0 port is also available on J2 and JA2 (R59 and R70 must be fitted) headers. The SCI5 port is available on J3 and JA6 headers..
6.5. Debug LCD Module
A debug LCD module is supplied to be connected to the connector marked 'LCD', so that the debug LCD module lies over J2. 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.
