SLVSCO4D July 2015 – February 2019 TPS65917-Q1
The user can request an asynchronous conversion. This conversion is not critical for start-of-conversion positioning.
The user must select the channel to be converted through the software and then request the conversion through the GPADC_SW_SELECT register. An GPADC_EOC_SW interrupt is generated when the conversion result is ready, and the result is stored in the GPADC_SW_CONV0_LSB and
A defect in the digital controller of TPS65917-Q1 device may cause an unreliable result from the first asynchronous conversion request after the device exit from a warm reset. Texas Instruments recommends that user rely on subsequent requests to obtain accurate result from the asynchronous conversion after a device warm reset.
