| Zusammenfassung: | The present invention relates to a data processing unit (1), comprising a central processing unit (7), a bus (13) coupled with the central processing unit to access a device via address and data lines coupled with the bus, a debug unit (11) being coupled to said bus, a protection unit (12) coupled with the bus and with the debug unit for protecting access on the bus. The protection unit is programmable to operate in a protecting mode in which the bus can be protected and in a debug mode in which a signal is sent to the debug unit, whereupon the debug unit generates a debug signal. |
