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, reference generator and a conversion result buffer. A window comparator with a lower and upper limits allows CPU-independent result monitoring with three window comparator interrupt flags.
Table 6-16 summarizes the available external trigger sources.
Table 6-17 lists the available multiplexing between internal and external analog inputs.
