4.3.1.1 Read Protection

When AHB masters other than the system controller issue read transactions to protected regions, the address and protection configuration is checked to determine whether the read is targeted to the protected region and if the read is allowed. If the read is not allowed, eNVM read command is not sent to the eNVM and an error is generated. For a specific AHB master to read a protected region, both the factory and user allowed bits must be set. Refer to Table 4-16 for information on eNVM access controls for AHB masters.
