Does anyone have any insight into making the WISP enter LPM3 for 30
microseconds and then waking up via TimerA. The code I've been trying
to use just doesn't seem to be working. I'll paste it below. Thanks.

-John
void sleep (unsigned short duration) {
_BIS_SR(GIE);

TACTL |= TACLR;
TACCR0 = duration;
TACCTL0 = CCIE;
TACTL = 0

LPM3;

TACTL |= TACLR;
TACCR0 = 0;
TACCTL0 = 0;
_BIC_SR(GIE);
}

#pragma vector=TIMERA0_VECTOR
__interrupt void TimerA0_ISR (void) {
TACTL &= ~TAIFG;
LPM3_EXIT;
}
------------------------------------

Refer to the MSP430 data sheet for LPM3
CPU, MCLK, SMCLK, DCO osc. are disabled
DC generator disabled
ACLK is active so I think you should configure TACTL to use clock source from
ACLK with Up mode

Hope it may be as I thought.
