5.1 Device Protected State

When the device is locked (the security bit is set), the MEM-AP access range is limited to the DSU’s external range. For more details, see Intellectual Property Protection in the PIC32CX-BZ2 and WBZ45 Family Data Sheet (DS70005504). It is recommended that the debugger first read the DSUEXT.STATUSB.PROT bit to handle this case. For more details on unprotecting the device, see Chip Erase.
