Registers
This section describes the registers of the MPU AHB
The MPU AHB module contains various registers to configure its operation, to monitor its status and to
read the information it has collected from the AHB master interface at the time of a memory protection
violation.
The MPU AHB module is allocated 1 KB of MCU address space for mapping the Configuration and Status
Registers (CSRs). The address area allocated to the MPU AHB and the CSRs in the MPU AHB are
explained in this section.
The suffix ‘n’ in the register name indicates that the register is an instance ‘n’ of the module.
