The F28379D controlCARD provides emulation and USB-to-UART adapter functionality on the controlCARD. This allows for a convenient method to debug and demo the F28379D MCU.

Note that the FTDI chip, its support circuitry, and associated isolation components are placed in Macro A, the left section of the controlCARD. Each of these components contains an additional A within the component reference designator (that is, A:R2 for resistor 2 in Macro A), see Figure 4-1.

Each F28379D controlCARD’s xds100v2 is programmed with a fixed serial number. If a debug session needs to involve two or more F28379D controlCARDs, each controlCARD needs to have a unique serial number and some need to be reprogrammed, see: https://software-dl.ti.com/ccs/esd/documents/xdsdebugprobes/emu_xds100.html (under Additional Information).

The configuration of the switches on A:SW1 determine whether the on-board emulator is active, whether an external emulator can be used, or whether the device will boot from FLASH/peripherals, see Table 5-1.
