The SCI1 and SCI2 port pins are also available on JA6 header.

The board is designed to accept a straight-through RS-232 male-to-female cable.

6.5. Debug LCD Module

The LCD module supplied with the RSK can be connected to the connector ‘LCD’ for use with the tutorial code. Any module that conforms

to the pin connections and has a KS0066u-compatible controller can be used. The LCD module uses a 4 bit interface to reduce the pin

allocation. No contrast control is provided; this must be set on the display module.

The pin allocation and signal names used on this connector are shown in Table 6-4:LCD Module connections

The module supplied with the MCU board only supports 5V operation.
