6.4 ADC66

ADC Module

Category

Functional

Function

ADC stops converting when ADC12ON bit is toggled during conversion

Description

Subsequent ADC conversions are halted if the ADC12CTL0.ADC12ON bit is toggled while the ADC is busy. The affected ADC modes are:

- sequence-of-channels

- repeat-single-channel

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

Workaround

Stop the ADC conversion by clearing the ADC12CTL0.ADC12ENC bit.
Check the ADC12CTL1.ADC12BUSY flag for 0 before toggling the ADC12CTL0.ADC12ON bit.
