I wasn't shure whether it was word or byte. I took the wrong guess,
but it
doesn't really matter in respect to the context.
you can program the flash in byte or word mode. i've used both.

Isn't a byte write to this memory just a word write with one byte set
to all ones?
To answer my own question... No. The flash can be written byte by byte
or word by word. I was getting confused with something else. Amongst my
own library of routines I have the following for 8 bit writes:
void flash_write_int8(int8_t *ptr, int8_t value)
{
_DINT();
FCTL3 = FWKEY; /* Lock = 0 */
FCTL1 = LOCK | WRT;
*((int8_t *) ptr) = value; /* Program the flash */
FCTL1 = FWKEY; /* Erase, write = 0 */
FCTL3 = FWKEY | LOCK;
_EINT();
}
