11.5.2.3 Operations

The PAC module allows the user to set, clear or lock the write protection status of all peripherals on all Peripheral Bridges.

If a peripheral register violation occurs, the Peripheral Interrupt Flag n registers (INTFLAGn) are updated to inform the user on the status of the violation in the peripherals connected to the Peripheral Bridge n (n = A,B,C ...). The corresponding Peripheral Write Control Status n register (STATUSn) gives the state of the write protection for all peripherals connected to the corresponding Peripheral Bridge n. Refer to 11.5.2.4 Peripheral Access Errors for details.

The PAC module also report the errors occurring at client bus level when an access to reserved area is detected. AHB Client Bus Interrupt Flag register (INTFLAGAHB) informs the user on the status of the violation in the corresponding client. Refer to the 11.5.2.7 AHB Client Bus Errors for details.
