AM273x Sitara Microcontrollers Silicon Errata

Abstract

This document describes the known exceptions to the functional specifications (advisories) of the AM273x microcontroller. This document may also contain usage notes. Usage notes describe situations where the device's behavior may not match presumed or documented behavior. This may include behaviors that affect device performance or functional correctness.
