Battery-operated the utility meter with a micro - controller and the base components for the realization of a state machine

摘要

Battery-operated the utility meter with a device, the apparatus comprising:Micro - controller with an independently operating state machine (14) via a bus system (12) is connected,a) wherein the micro - controller comprises a memory as a flash -, eprom, eeprom -, rom, -, ram - or - ram - memory (not shown) is designed,b) wherein said state machine directly via the bus system to the memory (10) of the micro - controller accesses; and an address generating means (20) and a status register as well as a data transfer means (22).b.1) the address generating means (20) an input (40, etc.), which forms the input of the state machine,b.2) of the output of the state register the output (30) forms the state machine,b.3) and the data transfer means causes the under the from the address generating means (20) address supplied in the memory (10) via a bus system independently stored data value without any control on the part of the micro - controller is read,b.4) and the addressed data are transferred to the state register.
