Function

ADC stops converting when successive ADC is triggered before the previous conversion ends

Description

Subsequent ADC conversions are halted if a new ADC conversion is triggered while ADC is busy. ADC conversions are triggered manually or by a timer. The affected ADC modes are:

- sequence-of-channels

- repeat-single-channel

- repeat-sequence-of-channels (ADC12CTL1.ADC12CONSEQx)

In addition, the timer overflow flag cannot be used to detect an overflow (ADC12IFGR2.ADC12TOVIFG).

Workaround

1. For manual trigger mode (ADC12CTL0.ADC12SC), ensure each ADC conversion is completed by first checking ADC12CTL1.ADC12BUSY bit before starting a new conversion.

2. For timer trigger mode (ADC12CTL1.ADC12SHP), ensure the timer period is greater than the ADC sample and conversion time.

To recover the conversion halt:

1. Disable ADC module (ADC12CTL0.ADC12ENC = 0 and ADC12CTL0.ADC12ON = 0)

2. Re-enable ADC module (ADC12CTL0.ADC12ON = 1 and ADC12CTL0.ADC12ENC = 1)

3. Re-enable conversion
