Talking to myself again :) There is a problem is in basic_clock.h DIVA0 is defined as 0x10 DIVA1 is defined as 0X20 DIVA_0 is defined as (0<<4) DIVA_2 is defined as (1<<4) My dumb code was BSCTL1 = DIVA1, which divided the clock by 4. BSCTL1 = DIVA0 would still divide it by 2. BSCTL1 = DIVA_0 is correct in my case. In the user manual, the bits are labled DIVA.1 and DIVA.0 That might be better than DIVA0 and DIVA1 in terms of making it more idiot proof.
