Abstract
An internal postage meter machine interface circuit is equipped with transmission and reception registers for storing data transmitted parallel and with a shift register for serial-to-parallel or parallel-to-serial conversion of transmitted data within an actuator/sensor control. Data are communicated serially between the meter and a register unit in the base. Sensors and actuators of the base are connected to the register unit. Sensor signals are shifted into the shift register of the actuator/sensor controller and are present therein so as to be fetchable in parallel. A sensor status register group for parallel data of the sensor signals of at least one sensor is provided as a reception register. At least one sensor status register and at least one interrupt control register are connected to a watchdog circuit in order to monitor the received bits of the sensor signals for status change in order to trigger an interrupt to the control unit, as warranted.
