Electronic circuit for managing the operation of peripheral devices of a watch

摘要

The circuit (1) has a processor (2) i.e. CPU, connected to a non-volatile memory (3) e.g. flash memory, and peripheral controllers (4) interacting with peripherals of a watch. Connection units constituted by multiplexers (6a, 6b) and a communication bus (7) connect the controllers, the processor and the memory to communicate information related to operation of a watch with each other. An initialization unit (8) i.e. programmable memory, acts on the controllers to initialize the controllers, and permits the controllers to execute operations independent of the processor and the memory. An independent claim is also included for a method for actuating an electronic circuit of a watch.
