CAUTION
The WDT should ideally be configured to generate a Hard Reset into the
system. A Soft Reset will reset the CPU, but leave the rest of the system and
peripherals unaffected. As a result if the WDT is configured to generate a Soft
Reset, the application should assume responsibility for the fact that a Soft
Reset can corrupt an ongoing transaction from the CPU into the system.
6.8.8 ADC14
The ADC14 module supports fast, 14-bit analog-to-digital conversions with differential and single-ended
inputs. The module implements a 14-bit SAR core, sample select control, reference generator and a
conversion result buffer. The window comparators with a lower and upper limit allow CPU independent
result monitoring through different window comparator interrupt flags.
The available ADC14 external trigger sources are summarized in Table 6-27.
The available multiplexing between internal and external analog inputs of ADC14 is listed in Table 6-
28,Table 6-29,Table 6-30.

(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 theADC14 chapter in the MSP432P4xx Family Technical Reference Manual for details on the
registers that contain the control bits listed in the table.
