Tiva^™ TM4C1294NCZAD Microcontroller
Register 31: ADC Sample Sequence Control 1 (ADCSSCTL1), offset 0x064
Register 32: ADC Sample Sequence Control 2 (ADCSSCTL2), offset 0x084
These registers contain the configuration information for each sample for a sequence executed with
Sample Sequencer 1 or 2. When configuring a sample sequence, the END bit must be set for the
final sample, whether it be after the first sample, fourth sample, or any sample in between. These
registers are 16-bits wide and contain information for four possible samples. See the ADCSSCTL0
register on page 1120 for detailed bit descriptions. The ADCSSCTL1 register configures Sample
Sequencer 1 and the ADCSSCTL2 register configures Sample Sequencer 2.

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.
4th Sample Temp Sensor Select
Value Description
0 The input pin specified by the ADCSSMUXn register is read
during the fourth sample of the sample sequence.
1 The temperature sensor is read during the fourth sample of the
sample sequence.

4th Sample Interrupt Enable
Value Description
0 The raw interrupt is not asserted to the interrupt controller.
1 The raw interrupt signal (INR0 bit) is asserted at the end of the
fourth sample's conversion. If the MASK0 bit in the ADCIM
register is set, the interrupt is promoted to the interrupt controller.
It is legal to have multiple samples within a sequence generate interrupts.
