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. Debug LCD Module
A debug LCD module is supplied on the RDK. The debug 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 RDK. The module supplied with the RDK only supports 5V
operation.

Switch
Mode/Debug Switch – Refer to Table 7-1 for details
When pressed, the RDK microcontroller is reset.
Connects to the Non-Maskable Interrupt (NMI) line.
Connects to an IRQ line for user controls.
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 E10A debugger.
E10A Mode Switch – This switch allows the user to reprogram the firmware for
the E10A debugger. In normal mode, the switch should be placed in the
direction shown by the arrow on the PCB, away from the board edge. Refer to
Chapter 8 for details on reprogramming the E10A.
