  • Method and apparatus for monitoring external events during a microprocessor's sleep mode
    Patent number: 5485625
    Abstract: An external oscillator is connected to the port accumulator of a microprocessor and supplies event signals to the microprocessor during its sleep state (following the execution of a STOP or WAIT instruction). Because the port accumulator within the microprocessor is capable of receiving and retaining a count during the microprocessor's mode, even though normal processing is suspended, the microprocessor is able to acquire information concerning external events which occur during the sleep mode. The technique may be used to indicate when the duration of the sleep mode exceeds a predetermined value.
