Yes — the device includes an internal oscillator, but the connectivity block supports external clock sources through the SCI interface. The internal oscillator is sufficient for most low-speed control applications.
The MSP430FR5724IRGET is programmed via the Spy-Bi-Wire (SBW) two-wire JTAG interface, which is standard on all MSP430 devices. TI's Code Composer Studio or IAR Embedded Workbench can be used with a compatible debug probe (e.g., MSP-FET or LaunchPad).
