Errata AM263Px Sitara™ Microcontroller Silicon Revision 1.0

Abstract

This document describes the known exceptions to the functional specifications (advisories). 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.
