DMADVR: Link/link_safer sync issue between MAIN and MCU
There is an error in the hookup for the parity checking of the PSIL Link signal between different DMA streaming domains (Main domain and MCU domain). During link state transitions (such as a link going down because an end point is put in to reset) the associated parity checker can flag false parity errors. The specified checkers cannot be disabled during normal operation or additional errors may go undetected.
An application must either disable the checkers and risk undetected errors or check any reported errors during known domain power transitions and ignore if it is the PSIL Link signal causing the error.
