Connectors
J1FSI Header
J2Type C USB Connector - Data Peripheral to MCU.

This connector supports DRP for dynamic switching between host mode (DFP) and device mode (UFP).

J3Emulation/UART connector/Power - USB-C connector used to provide XDS110 emulation and USB-to-UART (SCI) communication through MSP432 logic. S4 determines which connections are enabled to the MCU.
The USB-C connector also provides power on the controlCARD.
Table 2-2 LEDs
LEDs
D1Controlled by GPIO31 with negative logic (red).
D2Controlled by GPIO34 with negative logic (red).
D3Turns on (green) when 3.3V is supplied to the controlCARD from the on-board LDO (U4).
D4/D5LEDs controlled by XDS110.
D6Turns on (red) when 5V is supplied to the controlCARD
(5V can be supplied either through the USB-C connector or externally through the HSEC connector).
D7Turns on when JTAG logic is powered on (green).
D8Turns on when USB Data Connector (J2) is operating in host mode (DFP).
D9/D10Output of onboard transformer.
Table 2-3 Resistors and Capacitors
Resistors and Capacitors
R26-R52ADC RC input filter resistors: Series resistors which can be used to create an RC filter on the input of the ADC.
C29-C55ADC RC input filter capacitors: Optional capacitors, not populated by default, for the ADC RC filter of the input.
Table 2-4 Switches
Switches
S1 Boot Mode Switch: Controls the Boot Options of the F28P55x device, see Table 3-6. For a full description, see the device specific data sheet.
S2 Reset switch: Switch connected to the XRSn line of the F28P55x device. Pressing this button pulls the device reset low.
S3

ADC VREFHI Control Switch:

  • LEFT position - ADCs are configured to use an external voltage reference.

  • RIGHT (default) position - ADCs are configured to use an internal voltage reference which can be selected to be 0V to 3.3V or 0V to 2.5V.
S4 Isolated emulation and UART communication enable switches:
S4 Position 1 – USB JTAG Enable:
  • ON (default)– All 4 JTAG signals from the embedded XDS110 emulation logic are passed across the isolation barrier and connected to the MCU. This setting is valid when the MCU is being debugged or programmed using the embedded XDS110 emulator.
  • OFF – The 4 JTAG signals from the embedded XDS110 emulation logic are passed across the isolation barrier and are NOT connected to the MCU. This setting is valid when the device boots from FLASH, boots from a peripheral directly, or when an external JTAG emulator is used.
S4 Position 2 – USB UART communication enable:
  • ON (default)– The C2000 MCU GPIO28 is connected to the embedded XDS110. This allows UART communication to a computer COM port. However in this position, GPIO28 and GPIO29 are reserved for COM port use. The corresponding pins on the 180-pin controlCARD connector cannot be used for another function.
  • OFF – The C2000 MCU GPIO28 is NOT connected to the embedded XDS110. The corresponding pins on the 180-pin controlCARD connector can be used for another function.
