  • Method for communicating between a microprocessor and an interface circuit
    Patent number: 5671375
    Abstract: A protocol between a microprocessor (21) and an interface circuit (11). The interface circuit (11) transmits an enable signal (124) to the microprocessor (21). Upon receiving the enable signal (124), the microprocessor (21) transmits a set of pulses of a window signal (125) to the interface circuit (11), which in turn provides the microprocessor (21) with information concerning a circuit element (36) through a data signal (127). The microprocessor (21) initiates a command by transmitting a pulse of a command signal (126) to the interface circuit (11). The interface circuit (11) accepts and executes the command only if a predetermined chronological condition between the pulse of the command signal (126) and a corresponding pulse of the window signal (125) is satisfied. The microprocessor (21) identifies a malfunctioning interface circuit (11) by timing the enable signal (124) received from the interface circuit (11).
