6.2 ADC41

ADC Module

Category

Functional

Function

ADC conversion only triggers when sourced from TA0 and TA3 in LPM3/LPM4

Description

If the ADC clock is sourced from ADC12OSC (ADC12CTL1.ADC12SSELx = ADC12OSC), the reference module is not used (REFCTL0.REFON = 0), and the device is in LPM3/LPM4 mode, ADC conversion cannot be triggered when using Timer TB0, TA1 and TA2 (ADC12CTL1.ADC12SHSx).

Workaround

1. Use Timer TA0 or TA3 to trigger ADC conversion in LPM3/LPM4 mode

OR

2. Configure ADC clock to be sourced from ACLK (ADC12CTL1.ADC12SSELx = ACLK).

OR

3. Use Active/LPM0/LPM1/LPM2 mode

OR

4. Use the internal voltage reference (REFCTL0.REFON = 1)
