1.2.1 Configuring
the
hardware
The connectors must be configured correctly, as described in
The user must connect the USB port of the PC or notebook to connect the demonstration
board. The demonstration board should also be connected with the compatible slave
module using the PMBus connector pins.

ICC connector pins to re-program the MCU if needed. The connection is shown in the following
diagram:
Note:
This 6-pin connection is a customized ICC connector from the normal
connector. This modification is performed to achieve the low-form factor of
the board.
J8 (PMBus)
The following is the 10-pin PMBus interface connector description:
– Pin 1: Control signal 5
– Pin 2: Control signal 4
– Pin 3: Control signal 3
– Pin 4: Control signal 2
– Pin 5: VDD_OUT. Refers to slide switch position.
– Pin 6: Ground
– Pin 7: Control signal 1
– Pin 8: PMBus alert signal coming from the slave device.
– Pin 9: PMBus clock signal. This signal is always driven by the MCU in this demonstration board.
– Pin 10: PMBus data signal. This signal is bi-directional.
Note:
The voltage on the control lines is either 5 V or 0 V depending on the
selection made through the GUI.
