Hardy,
It started to work when I included "msp430x241x.h" for correct ISR
addresses and build all on circuit board.
There was also problem with digital clock register's setup - that's why
it did not work before even when I used proper header file. I've added
BCSCTL1 = XT2OFF|XTS|DIVA_0;
BCSCTL3 = LFXT1S1;
There is some differences in clock's settings against 1612 which I have
missed.
Thank you all very much for your help!

Dmitry
