WARNING: When the controlCARD is used in a high-voltage setup, confirm that the voltages and isolation requirements are identified and understood prior to energizing the board or simulation. When energized, the controlCARD or components connected to the controlCARD cannot be touched. Furthermore, the capacitor C7:A must be removed to minimize the possibility of leakage current flowing across the isolation barrier of the controlCARD.

Table 6-1 Hardware Connections
Connectors
J1:AEmulation/UART connector/Power - USB-C connector used to provide XDS110 emulation and USB-to-UART (SCI) communication through MSP432 logic. S1:A determines which connections are enabled to the MCU.
The USB-C connector also provides power on the controlCARD.
LEDs
LED1:ATurns on (red) when 5 V is supplied to the controlCARD
(5 V can be supplied either through the USB-C connector or externally through the HSEC connector)
LED2:A/LED3:AJTAG/UART RX/TX toggle indicator (blue)
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 (U3)
Resistors and Capacitors
R23-R38ADC RC input filter resistors: Series resistors which can be used to create an RC filter on the ADC's input.
C29-C44ADC RC input filter capacitors: Optional capacitors, not populated by default, for the ADC input's RC filters.
Switches
S1:AIsolated emulation and UART communication enable switches:
S1:A Position 1 – USB JTAG Enable:
  • ON (default) – All 4 JTAG signals from the embedded XDS110 emulation logic are passed across the isolation barrier. By default, only the TMS and TCK signals are connected to the MCU. This setting is valid when the MCU is being debugged or programmed using the embedded XDS110 emulator in 2-pin cJTAG mode. To enable full JTAG mode, S2:A must be additionally configured.
  • OFF – The 4 JTAG signals from the embedded XDS110 emulation logic are NOT 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.
S1:A Position 2 – USB UART communication enable:
  • ON (default) – The C2000 MCU GPIO28 and GPIO29 are 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 and GPIO29 are NOT connected to the embedded XDS110. The corresponding pins on the 180-pin controlCARD connector can be used for another function.

S2:A

GPIO35/TDI and GPIO37/TDO Function Switch:

This switch selects the function of the GPIO35 and GPIO37 pins

  • UP position - GPIO35 and GPIO37 are connected to HSEC pins 6 and 8, respectively. This setting is valid when using these pins as TDI and TDO in full JTAG mode.
  • DOWN position (default) - GPIO35 and GPIO37 are connected to HSEC pins 80 and 82, respectively. This setting is valid when using these pins as GPIO.

S1

GPIO10 and GPIO11 HSEC Connection Switch:

This switch selects which HSEC pins the GPIO10 and GPIO11 pins are connected to

  • UP position - GPIO10 and GPIO11 are connected to HSEC pins 62 and 64, respectively.
  • DOWN (default) position - GPIO10 and GPIO11 are connected to HSEC pins 61 and 63, respectively.
S3GPIO19/X1 and GPIO18/X2 Function Switch:

This switch selects the function of the GPIO18 and GPIO19 pins

  • UP position (default) - GPIO18 and GPIO19 are connected to the on-board crystal (Y1). This setting is valid when using the external crystal.
  • DOWN position - GPIO18 and GPIO19 are connected to HSEC pins 71 and 73, respectively. This setting is valid when using the on-chip internal oscillator.
S4Boot Mode Switch: Controls the Boot Options of the F280015x device, see Table 6-2. For a full description, see the device-specific data manual.
S5Analog Configuration Switch: This switch selects the source for VREFHI and the routing of the A10/C10 ADC channel.
S4 Position 1 (left switch) –

ADC channel A10/C10 HSEC pin selection

  • UP position – Channel A10/C10 goes to HSEC pin 34
  • DOWN position (default) – Channel A10/C10 goes to HSEC pin 28
Position 2 (right switch) -

ADC voltage reference selection

  • UP position – External voltage reference
  • DOWN position (default) – Internal voltage reference

Note that additional software configuration is required to enable the ADC internal or external voltage reference.

Test Points
TP1:AUSB 5.0 V input: This is the 5 V supply from the USB-C connector
TP2:AUSB GND input: This GND from the USB-C connector
TP1HSEC 5.0 V input: 5.0 V input provided to the controlCARD
TP2Unfiltered 3.3 V: Provides power to the F280015x device
TP3MCU 1.2 V: VDD 'core supply' to the F280015x device. Note that this controlCARD has been designed to use the internal voltage regulator by default. The internal voltage regulator can be disabled by removing R5 and populating R4. An external 1.2-V source must be supplied through the HSEC connector.
TP4Device Ground
TP5XRSn of F280015x device: Connected to the XRSn pin of the F280015x device.
Note: On the front of the controlCARD, test points are indicated by their TPx number.
On the back of the controlCARD, test points are indicated by their signal.
