Abstract
The electronic postage meter includes a printing unit which is responsive to a plurality of motors for printing of a postage indicia in response to control circuit. The control circuit is comprised of a programmable microprocessor in bus communication with an accounting means having memory units for accounting for the postage printed by the printing unit responsive to the programming of the microprocessor. An integrated circuit includes an address decoding module means for generating a unique combination of ASIC control signals in response to a respective address placed on the bus by the microprocessor. A timer register is responsive to ones of the control signals from the address decoding module to enable writing of the timer data into the timer registers by the microprocessor. The timer unit is responsive to the timer data for generating one of a plurality of timing signal in accordance with timer data. The data also includes motor data. Prime motor register units are responsive to other ones of the control signals from the address decoding module to enable writing of the motor data into the timer registers by the microprocessor. A motor control unit is responsive to the motor da…
