15.5.1.1 Operations

The PAC module allows the user to set, clear, or lock the write protected status of any peripherals. If a peripheral access violation occurs, the Peripheral Interrupt Flag registers (INTFLAGx, x=A, B, or C) are updated to inform the user which peripherals have had access violations. The corresponding Peripheral Write Control Status n register (STATUSx) gives the state of the write protection for all peripherals.

The PAC module also reports any errors occurring at client bus level when an access to a 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 AHB Client Bus Errors for details.
