Hi...actually I am working in a project entitled "ecg wireless node". I am using msp430fg4618 target board. So My question is may I solder a 16 MHz crystal instead of 32.768 KHz crystal physically on this target board as a ACLK (by the way soldering option is there on Xin-Xout) ....i.e. ACLK is low freq source ...so If I use 16MHz in place of 32.768 KHz is there any issues arise.. (except low power mode issues...).
