User Manual
for S32K1XX ADC Driver
2.1 Requirements
Requirements for this driver are detailed in the AUTOSAR 4.0 Rev0003 Adc Driver
Software Specification document (See Table Section 1.5 ).
2.2 Driver Design Summary
The ADC Driver initializes and controls the internal Analogue to Digital Converter Unit(s)
of the microcontroller. It provides services to start and stop a conversion respectively to
enable and disable the trigger source for a conversion. Furthermore it provides services
to enable and disable a notification mechanism and routines to query the status and
result of a conversion. The ADC Driver shall work on so called ADC Channels. An
ADC channel combines an analogue input pin, the needed ADC circuitry itself and a
conversion result register into an entity that can be individually controlled and accessed
via the ADC Driver. The driver provides a service for Streaming management results and
for De-Initialization of circuits.
