i've not checked the 2330 data sheet yet. is there something
different in the DCO,
AFAICT, the DCO works the same. I use a software FLL scheme to
lock the DCO at 16X ACLK, and the code that does that is
identical to what I used on the 'F149. I have measured SCLK
and verified that it's at the frequency I want, so I know the
DCO adjust routine is working.
yep, the DCO is the standard F2xx module (i've now looked at the data
sheet and errata). while the F1xx FLL is almost identical there are some
small differences. one is that it has one RSEL bit more and that the
ranges are slightly different compared to a F1xx.
(no problem for your FLL code)
I've never looked at the at the flash controller specs. My
applications generally can't burn flash because they're running
at 1.9V.
looks like these are the standard F2xx specs
as these module seem to be the standard ones, i suspect that the
frequency adjustment of msp430-jtag fails leading to a wrong flash
clock. can you send me the output of "msp430-jtag -DDD -e" ?
