Register 2: ADC Raw Interrupt Status (ADCRIS), offset 0x004
This register shows the status of the raw interrupt signal of each sample sequencer. These bits may
be polled by software to look for interrupt conditions without sending the interrupts to the interrupt
controller.
ADC Raw Interrupt Status (ADCRIS)
ADC0 base: 0x4003.8000
ADC1 base: 0x4003.9000
Offset 0x004

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Digital Comparator Raw Interrupt Status
Value Description
1 At least one bit in the ADCDCISC register is set, meaning that
a digital comparator interrupt has occurred.
0 All bits in the ADCDCISC register are clear.

SS3 Raw Interrupt Status
Value Description
1 A sample has completed conversion and the respective
ADCSSCTL3 IEn bit is set, enabling a raw interrupt.
0 An interrupt has not occurred.
This bit is cleared by writing a 1 to the IN3 bit in the ADCISC register.

SS2 Raw Interrupt Status
Value Description
1 A sample has completed conversion and the respective
ADCSSCTL2 IEn bit is set, enabling a raw interrupt.
0 An interrupt has not occurred.
This bit is cleared by writing a 1 to the IN2 bit in the ADCISC register.
