Abstract (en)
[origin: EP2063328A2] The circuit (1) has a processor (2) i.e. CPU, connected to a non-volatile memory (3) e.g. flash memory. Connection units constituted by multiplexers (6a, 6b) and a communication bus (7) connect peripheral controllers (4), the processor and the memory to communicate information relating to operation of a watch with each other. An initialization unit (8) i.e. programmable memory, acts on the controllers to initialize the controllers by sending data without intervention of the processor and by permitting the controllers to execute operations independent of the processor and the memory. An independent claim is also included for method for actuating an electronic circuit of a watch.
