VDDI / VIN
A three-pin terminal block serves as the input terminal for the main power between 2.7 and 5.5V to operate the KIT34704AEPEVBE, as well as providing access to the reference voltage VDDI generated by the MC34704A to supply configuration voltages.
Regulator 1 uses a three-pin terminal block to provide GND reference and VO1 output at 5V with a maximum current capability of 500mA. It also provide access to the internal Gate voltage VG for monitoring purposes
Regulator 2 through 8 use a two-pin terminal block to provide each GND reference and VOx respectively. To learn how to configure the output voltage on each regulator, please refer to the MC34704 datasheet that can be found at www.freescale.com
The following diagram shows each of the terminals and its respective output voltage identificator.

8.3 Starting up the KIT34704AEPEVBE
To Start working with the KIT34704AEPEVBE, provide an input voltage between 2.7V and 5.5V connecting the (+) probe to the VIN terminal and the (-) probe to the GDN terminal on the Input power terminal block. Turn on the power supply and the LEDRST should turn on.
At this moment the three stand alone regulators (REG2, REG3 and REG4) should be providing pre-configured output voltage. To operate the rest of the MC34704A functions, it is necessary to use I
Section 11 will discuss how to interact with the KIT34704AEPEVBE using the Graphical User Interface developed by freescale to fully operate the MC34704A.

The J1 jumper should be disconnected only while JB8 is being programmed. Since the MCU is already programmed, J1 should be connected all the time, so the board operates properly. It is not recommended to program the JB8 due to pre loaded program will be erased and it will not longer operate correctly.

10 KIT34704EPEVBE Graphical User Interface
A graphical user interface has been developed to allow the user to fully interact with the KIT34704AEPEVBE using a Windows XP based computer.
10.1 Installing the KIT34704A GUI and KITUSBI2CEVME driver
Before connecting the KITUSBI2CEVME, install the Graphical User interface by double clicking into the Setup.exe file provided on the CD included with the kit; follow the instructions until the software is fully installed. Microsoft Frameworks 2.0 is required, if it is not previously installed the software will perform this installation prior to the MC34704A GUI software.
Connect the KITUSBI2CEVME to the USB port on the host computer for the first time, and the PC will try to recognize the USB device; when the driver selection window appears select the option “Install from a list or specific Location”.

b) GRPC/E Power Sequencing: allows to change the power sequencing for regulators
5, 6 and 7, please refer to I2C register section on Datasheet for more details on how this works.
c) Shutdown Hold time: Program the waiting time for a shut
down after the Hardware
shutdown push button is pressed.
d) REG6/7/8 FSW
