USING THE EVALUATION BOARD
O PERATING A SSUMPTIONS
The following are the basic assumptions for
the operation of the XCM.
? Only one I 2 C Master is active at any time on
the customer board. The user must ensure
that only 1 master is active on the I 2 C lines
at the same time. This could entail Host in
Reset, Host communication lines disabled,
etc.
C OMMUNICATION WITH THE XCM
If the XCM is connected to the PC before
starting the PowerArchitect TM software, the
software should recognize the presence of the
board automatically. If the board is connected
after the software is started, the user will need
to click on “File”, then “Board Search” for the
software to find the board.
Once the board is identified, the software will
add a tab called “XCM” as shown in Figure 3.
? The user
signals to
XCM JP4.
GND must
must connect the appropriate
from the system board to the
At a minimum; SDA, SCL, and
be connected.
? VIN and ENABLE must also be connected, if
the customer wants the XCM board to
operate in “Standalone Mode”.
Using I 2 C Communication
The XCM has an on board linear regulator to
provide power to the uC and provides power
to the I 2 C lines. The internal pull-up resistors
are 4.7kohm. By changing the position of the
jumpers on JP2 and JP3, the pull-up resistors
can be connected to either the 3.3V provided
on the XCM or to the I 2 C Power connected to
JP4 Pin 5. In Figure 2 the jumpers are
configured to use the on board 3.3V. Moving
them to the other position connects the pull-
up resistors to the external I 2 C Power.
IMPORTANT: When using the XCM with
XRP7713EVB or XRP7714EVB demo boards,
the jumpers should be configured to use the
3.3V provided on the XCM. When using with
the XRP7724EVB board, the jumpers should
be moved to the other position to use the
pull-up resistors already installed on the
XRP7724EVB.
If the system board already has pull-up
resistors, then the jumpers can simply be
removed. This is the most likely scenario for
a system intended to interact with the
programmable features of the Power XR device
on the system board.

LED I NDICATORS :
There are 6 LEDs on the board.
There are four LEDs grouped in the upper left
hand corner of the board as shown in Figure 3.
These are defined as:
DS3: USB Operation
GUI is communicating to XCM (solid on when
USB is connected)
DS4: Reconfig Mode
The XCM will boot load the supported device
with the stored configuration the ENABLE pin
transitions from Low to High.
DS1: USB Activity
Flashes based upon the USB activity between
the XCM and the PC.
