1322x Network Node Reference Manual, Rev. 1.1
4-4 Freescale Semiconductor
4.5 LEDs, Switch, Buttons and Joystick
The Network Node contains a total four red LEDs and one green LED
• The four red LEDs are driven by the MCU and controlled by the software application.
• As previously stated, the green LED is directly connected to the on-board regulator and acts as a
"Power On" indication.
As also previously stated, SW7 is an on/off slide switch that connects the power supplies.
There are five pushbuttons total.
• One pushbutton (SW5) is separate and provides a master hardware Reset.
• Four additional pushbuttons are connected to the MCU GPIO for software application. These
buttons all have interrupt generation capability
A joystick (SW6) is also provided.
• The joystick is a 4-direction TACT Switch with Center Push.
• The 4-directional TACT switches are connected in parallel with the four user pushbuttons.
• The center push switch is separate and does not have interrupt generation capability
