2.6.7
Analog to Digital Converter Module (ADC)
The PXN20 ADC features the following:
10-bit A/D resolution
0–VDD common mode conversion range
Supports conversions speeds of up to 1 µs
Internally multiplexed channels
— 10-bit
 2 least significant bits (LSB) accuracy (TUE) available for 16 channels
— 10-bit
 3 LSB accuracy (TUE) available for remaining channels
— Dedicated result register available for every internally muxed channel
Externally multiplexed channels
— Internal control to support generation of external analog multiplexor selection
— Four internal channels optionally used to support externally multiplex inputs, providing
transparent control for additional ADC channels
— Each of the four channels supports up to 8 externally muxed inputs
Three independently configurable sample and conversion times for high occurrence channels,
internally muxed channels and externally muxed channels
Right-aligned result format
Support for one-shot, scan and injection conversion modes
Traceability of each channels with conversion result.
Injection mode status bit implemented on adjacent 16-bit register for each result
Independently configurable parameters for channels:
—Offset refresh
— Sampling
Cross Triggering support (PXN21 only)
— Internal conversion triggering from periodic interrupt timer (PIT) or timed I/O module
(eMIOS200) via Cross Triggering Unit (CTU)
— One input pin configurable as external conversion trigger source
Four configurable analog comparator channels offering range comparison with triggered alarm
Supports operation of ADC using internal 16 MHz RC oscillator
All unused analog pins available as general purpose input pins
Selected unused analog pins available as general purpose output pins
Power-down mode
Supports for DMA transfer of results
