This document describes these features and provides general recommendations for their use. Associated application notes and other applicable documents that provide more details are listed for reference.  \nSince the RA6M5 is a general-purpose MCU, this Security Manual cannot provide specific guidance for all possible use cases, nor can it offer system-level security recommendations. It is highly recommended that the application developer conduct a security analysis of the system into which the RA6M5 is integrated and create a threat model and security policy for the system and for the RA6M5 , for example, using the ISO/SAE 21434 Threat Analysis and Risk Assessment (TARA) approach. It is the application developer’s responsibility to decide what RA6M5 security features are necessary for the end product and to implement them appropriately.  \nAlthough this Security Manual describes the best secure practices for configuring the RA6M5 at the time of its release, the microcontroller threat landscape is constantly changing and evolving.
