5.4.4 LEDs
Two LEDs are provided on the EK-RA6M2 board. U1 is the Main MCU, and directly controls LED1. See
Figure 8 for LED1 location, Figure 11 for LED2 location, and Figure 10 for LED2 circuit. U2 is the J-Link
MCU, and it controls the red LED in LED2.
Figure 16. LED1 Control Circuit
The behavior of the LEDs is described in the following table.

N.A.
To disconnect the User LED from the MCU signal P106, the copper jumper E3 must be
open.
5.4.5 Switches
Two miniature, momentary, mechanical push-button type SMT switches are mounted on
the EK-RA6M2 board. Pressing the RESET Switch generates a reset signal to restart the
Main MCU.
To disconnect the User Switch from the MCU signal P105/IRQ0, copper jumper E4 must
be open.
