Serial Port; Lcd Module - Renesas R8C/Tiny Series User Manual

6.4. Serial port

This RSK provides two serial ports to the user. The serial port 1 has already been configured for use. To use serial port 2 the user needs to
configure the option links as given in Table 6-3.

6.5. 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 'JA1' and 'JA5'.
Care should be taken to ensure the pins are inserted correctly into 'LCD' connector. 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 6-4 shows the pin allocation and signal names used on this connector.
