Kit Introduction
KIT33812EKEVBE Evaluation Board (EVB) is an easy-to-use circuit board used to exercise all the
functions of the MC33812 Multifunctional Ignition and Injector Driver. A Personal Computer (PC)
communicates to the EVB through a USB/SPI Dongle (KITUSBSPIDGLEVME) connected to the PC’s
USB port. The Freescale SPIGen program provides the user Interface to the MC33812 EVB’s SPI port
and is used to send commands to the IC.
