Register Map
Table 11-2 lists the ADC registers. The offset listed is a hexadecimal increment to the register’s
address, relative to the ADC base address of 0x40038000.
For each sample in the sample sequence, configure the corresponding input source in the
ADCSSMUXn register.
For each sample in the sample sequence, configure the sample control bits in the
corresponding nibble in the ADCSSCTLn register. When programming the last nibble, ensure
that the END bit is set. Failure to set the END bit causes unpredictable behavior.
If interrupts are to be used, write a 1 to the corresponding MASK bit in the ADCIM register.
Enable the Sample Sequencer logic by writing a 1 to the corresponding ASEN bit in the
ADCACTSS register.
