static

Internal function for analog test.

This test writes a value to the DAC, and checks that the ADC readouts are within the expected range, which is set with CLASSB_ADC_DEV.

Parameters

dacptr	Base address for registers of DAC module to test.
adcptr	Base address for registers of ADC module to test.
dac_out	Output value to test the DAC with.
adc_assert	Expected ADC value to measure.
