JTAG
A standard MSP430 14-pin JTAG header supports communication to program and debug the MCU (see
). If power is supplied by the JTAG header, set the POW_SEL switch the bottom position (JTAG).
If external power is used, set the switch to the top position (External).

Communications
The EVM430-FR6043 supports UART, I

C, and Spy-Bi-Wire interfaces.
J3 connects JTAG TX and RX (UART). To use this interface with the on-board eZ-FET circuit, place
jumpers on the J3 TXD and RXD pins (see
