6.1. Switches
There are four switches located on the Renesas Starter Kit. The function of each switch and its connection are shown in Table 6-1.
Switch Function Microcontroller
RES When pressed, the board microcontroller is reset. RESET Pin 7
SW1/BOOT* 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.
INT0 Pin14
(Port 8, pin 3)
SW2* Connects to an IRQ input for user controls. INT1 Pin17
(Port 8, pin 4)
SW3* Connects to the ADC trigger input. Option link allows connection to
IRQ input. The option is a pair of 0R links. ADTRG Pin 36
(Port 1, pin 5)
OR
INT3 Pin34
(Port 1, pin 7)

*Refer to schematic for detailed connectivity information.
6.2. LEDs
There are six LEDs on the Renesas Starter Kit 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.
