6.3. Potentiometer
A single turn potentiometer is connected to AN2.4 (P9.3) of the microcontroller. This may be used to vary the input analog voltage value to
this pin between AVCC and Ground.
6.4. Serial port
The microcontroller programming serial port 1 is connected to the E8a connector. This serial port can optionally be connected to the RS232
transceiver as well by fitting zero Ohm option resistors and fitting the D connector. In addition the RS232 transceiver should be enabled.
The connections to be moved are listed in the table 6-3.
A Secondary serial port is connected to the application headers.
6.5. LCD Module
A LCD module is supplied to be connected to the connector J8. This should be fitted so that the LCD module lies over J1. Care should be
taken to ensure the pins are inserted correctly into J8.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.
