4 Kit operation
This section explains the operation, programming, and debugging modes of the kit. It also describes the
procedure for programming and debugging the application firmware on the kit in detail.
The EVK is designed to work as a USB PD DRP and the firmware associated with the USB PD dual-role power
(DRP) CAPSENSE™ code example supported in ModusToolbox™ software is downloaded in the factory on the
kit.

USB PD sink operation

The EVK supports up to a maximum contract of 28 V, 5 A (140 W) in the Sink mode. The Type-C port (J10 or J14)
on the EVK automatically switches to the Sink mode when a Type-C adapter is connected to it.

Figure 19 Test setup in Sink mode
Follow these steps to operate the EVK in the USB PD Sink mode:
1. Set the kit in Operational mode by placing a jumper shunt on the power selection jumper (J5) at position 1-2
to select the 3.3 V LDO (powered by the USB-C power adapter) as the power source for the EVK.
2. Connect the USB PD Type-C port (J10 or J14) of the board to the USB-C power adapter using the USB Type-C
cable.
3. Confirm that the power LED (LED4) glows green and the user LED (LED3 for J10 and LED5 for J14) blinks
green at a rate of 1 Hz.
4. Measure the DC_OUT voltage by connecting a multimeter to the terminal block (J9 for Port 0 and J15 for
Port 1). Confirm that the DC_OUT voltage value is within the 4.75 V–29.4 V range. The actual value is
determined by the maximum voltage, which the USB-C power adapter can supply. Only power adapters that
support USB PD EPR can provide PD contract voltages greater than 20 V.
5. If Port 0 is connected to the power adapter, the CAPSENSE™ buttons and sliders can be used to renegotiate
the PD contract at different voltage levels based on the connected USB-C power adapter capability. Touch
CAPSENSE™ Button 0 to negotiate up 20 V at 900 mA SPR PD contract or touch CAPSENSE™ Button 1 to
negotiate up to 28 V at 5 A EPR PD contract. Touch CAPSENSE™ slider 0, 1, 2, 3, or 4 to negotiate PD
contracts up to 5 V, 9 V, 12 V, 15 V, or 20 V respectively at 900 mA.
