Mspdebug can be used to program this device using its `eZ FET lite' interface, however, it doesn't appear to work reliably.

Hoever, with the tilib interface mspdebug does seem to work reliably, however, it doesn't operate if ez-fet mode was attempted before-hand.

MSP430 Flasher can program this device using TI TEXT files.
