(1) If an internal source is marked as NA or Reserved, it indicates that only the external source is
available for that channel.
(2) Refer to the ADC14 chapter in the MSP432P4xx Family Technical Reference Manual for details on the
registers that contain the control bits listed in the table.

6.8.9 Comparator_E (COMP_E)
The primary function of the COMP_E module is to support precision slope analog-to-digital conversions,
battery voltage supervision, and monitoring of external analog signals.
There are two COMP_E modules available on the MSP432P401x devices.
6.8.10 Shared Reference (REF_A)
The REF_A is responsible for generation of all critical reference voltages that can be used by the various
analog peripherals in the device. The reference voltage from REF_A can also be switched on to device pin
for external use.
6.8.11 CRC32
The CRC32 module produces a signature based on a sequence of entered data values and can be used
for data checking purposes. It supports both a CRC32 and a CRC16 computation.
• The CRC16 computation signature is based on the CRC16-CCITT standard.
• The CRC32 computation signature is based on the CRC32-ISO3309 standard.
6.8.12 AES256 Accelerator
The AES accelerator module performs encryption and decryption of 128-bit data with 128-bit, 192-bit, or
256-bit keys according to the Advanced Encryption Standard (AES) (FIPS PUB 197) in hardware.
