6.1. Switches
There are four switches located on the CPU board. The function of each switch and its connection are shown in Table 6-1.
*Refer to schematic for detailed connectivity information.
6.2. LEDs
There are six LEDs on the RSK board. The green ‘POWER’ LED lights when the board is powered. The orange BOOT LED indicates the
device is in BOOT mode when lit. The four user LEDs are connected to an IO port and will light when their corresponding port pin is set low.
Table 6-2, below, shows the LED pin references and their corresponding microcontroller port pin connections.
6.3. Potentiometer
A single turn potentiometer is connected to AN8 (PC.0) of the microcontroller. This may be used to vary the input analogue voltage value to
this pin between AVCC and Ground.
6.4. Serial port
The on-chip emulator port is connected to the E8a connector. Serial port SCI3_2 can optionally be connected to the E8 connector by fitting
option resistors. The connections to be fitted are listed in the table 6-3.

Switch
When pressed, the RSK microcontroller is reset.
Connects to an IRQ input for user controls.
The switch is also used in conjunction with the RES switch to place the device in
BOOT mode when not using the E8a debugger.
Connects to an IRQ line for user controls.
Connects to the ADC trigger input. Option link allows connection to IRQ line.
The option is a pair of 0R links. For more details on option links, please refer to
