26.5.2.2 Operations

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

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. See Peripheral Access Errors from Related Links.

The PAC module also report the errors occurring at client bus level when an access to reserved area is detected. AHB Subordinate Bus Interrupt Flag register (INTFLAGAHB) informs the user on the status of the violation in the corresponding client. See AHB Subordinate Bus Errors from Related Links.
