RT600 secure GPIO and usage
■This application note explains how a secure GPIO must be used and configured in secure mode. It also demonstrates how a non-secure mode can access a peripheral’s pin state regardless of the pin function whether the peripheral function is secure or non-secure which results in secure information leakage.
●Overview:
■RT600 has secure GPIO module whose usage is closely related to normal GPIO, TrustZone, and secure AHB Controller. This section briefly introduces these functions. For more information on these functions, refer to RT600 User Manual.
