PRODUCTION DATA
The ADC12_B module supports fast 12-bit analog-to-digital conversions with differential and single-ended inputs. The module implements a 12-bit SAR core, sample select control, a reference generator, and a conversion result buffer. A window comparator with lower and upper limits allows CPU-independent result monitoring with three window comparator interrupt flags.
Table 9-18 lists the available external trigger sources. Table 9-19 lists the available multiplexing between internal and external analog inputs.
