System and method for implementing a hidden address in a communication module |
摘要 |
A module that detects a password at a hidden address in order to implement a change in an address scheme. The module includes a bus and a memory having a memory address which is coupled to the bus. The module further includes an interface-comparing circuit that monitors data traffic on the bus and receives a predetermined password. The module still further includes a password-comparing circuit which is coupled to the interface-comparing device and allows access to the memory in response to the interface-comparing circuit receiving the proper predetermined password. Such a module can implement a change in the module's configuration or operating characteristics. Such changes include acknowledging a new memory address into the address scheme, unacknowledging an existing memory address in the address scheme and downloading a new operating program having a new address scheme to a controller coupled to a second bus.
