Abstract (en)
[origin: EP0694886A1] The franking machine has a microprocessor (1) connected by an address bus (11) and a data bus (10) to a non-volatile memory (2) that holds the operating program for the franking machine. The non-volatile memory is flash memory with its address space divided into multiple sectors (S1-S8) selectively addressable from the address bus. An address decoder circuit (3) is connected between the address bus and a terminal (WE) of the memory circuit authorising or inhibiting writing to the memory. The address decoder is configured so the microprocessor is blocked from writing when the decoding circuit detects a control signal a first level and is allowed to write when the control signal is at the second level. The control signal level is set by an externally accessible removable link (4). <IMAGE>
