  • Data collection terminal interrupt structure
    Patent number: 4669057
    Abstract: A data collection terminal includes a microprocessor, a memory and a number of devices coupled to a system bus. An interrupt controller processes the device interrupt requests by sending a vector address out on the system bus to enable the microprocessor to branch to a microprogram to process the interrupt request. Apparatus is provided to receive the vector address to generate an interrupt clear signal for those interrupts which are transitory in nature. Typical examples are a document being inserted in a device or a card seated in a device.
