Patent attributes
An apparatus and method for interrupt source signal allocation is provided. An interrupt controller may include an interrupt source allocation unit, an interrupt pending register, a control register, a priority register, and/or an interrupt request signal generator. The interrupt source allocation unit may output one or more interrupt source signals based on one or more priorities, and may allow a user to move an individual interrupt source signal without moving other interrupt source signals. The interrupt pending register may set bits in one or more registers corresponding to the interrupt source signals. The control register may control and transmit the interrupt source signals corresponding to the set bits. The priority register may determine the priorities of the interrupt source signals. The interrupt request signal generator may output an interrupt request signal in response to one or more interrupt source signals received from the priority register.
