Analog Peripherals
- Analog-to-Digital Converter with
Computation and Context Switching:
- Up to 43 external
channels
- Automated math functions on input signals:
- Averaging, filter calculations, oversampling
and threshold comparison
- Four Separate Contexts
(settings and results) saved and accessible separately
- Contexts can be accessed
through firmware or DMA
- Operates in Sleep
- Five internal analog channels
- Hardware Capacitive Voltage Divider (CVD) Support:
- Adjustable sample and hold capacitor
array
- Guard ring digital output drive
- Automates touch
sampling and reduces software size and CPU usage when touch or
proximity sensing is required
- 8-Bit Digital-to-Analog Converter
(DAC):
- Buffered output available on
two I/O pins
- Internal connections to ADC
and Comparators
- Two Comparators (CMP):
- Four external inputs
- Configurable output
polarity
- External output via Peripheral Pin Select
- Zero-Cross Detect (ZCD):
- Detect when AC signal on pin crosses ground
- Voltage Reference:
- Fixed Voltage Reference with
1.024V, 2.048V and 4.096V output levels
- Internal connections to ADC,
Comparator and DAC
