MSP430FR2100: ADC Busy Bit Stuck High

Part Number: MSP430FR2100

I'm trying to get the ADC working on the MSP430FR2100. I have the following register settings:

ADCCTL1 = 0x00;
ADCCTL2 = 0x10;
ADCMCTL0 = 0x01;
ADCCTL0 = 0x12;

I then OR in a 1 into ADCCTL0 to set the ADCSC bit, which should start a sample-and-conversion cycle.

Then, I wait for ADCBUSY bit in ADCCTL1 to go low....but it never does.

Is there a step I'm forgetting to do?
