  • Interrupt control circuit, circuit board, electro-optic device, and electronic apparatus
    Patent number: 7730250
    Abstract: An interrupt control circuit includes: a section that generates an interrupt signal for requesting an interrupt in response to occurrence of a plurality of interrupt causes; a section that generates an interrupt vector signal for indicating a storing destination of an interrupt processing program corresponding any of the plurality of interrupt causes; a section that outputs the interrupt signal and the interrupt vector signal to an interrupt process executing circuit; and a section that controls the interrupt signal and an output value of the interrupt vector signal in sync with an interrupt acceptance signal input from the interrupt process executing circuit, the interrupt acceptance signal representing a condition in which an interrupt process is acceptable.
    Type: Grant
