MSP430 flash memory is in-system programmable (ISP) without the
need for additional external voltage. The CPU can program its
own flash memory. The flash memory write/erase modes are
selected with the BLKWRT, WRT, MERAS, and ERASE bits and are:
- Byte/word write
- Block write
- Segment Erase
- Mass Erase (all main memory segments)
- All Erase (all segments)
AFAIK, the flash controller is the same in all current parts.
