 ## Setup
 
 The following steps explain the procedure for setting up the hardware for three-phase sequence detection using AVR128DA64 microcontroller. The AVR device is connected to the STK600 using an innovative routing (STK600-RC064AVR-108) and socket (STK600-TQFP64-2) card sandwich system, which routes the I/O pins from the device to the appropriate hardware. Figure 1 below the listed instructions shows the hardware setup used for the application demo.
