Abstract
A serial interrupt method includes receiving a blank serial interrupt request signal (SerIRQ) and a level signal of a peripheral, based on the blank SerIRQ, generating an indication SerIRQ including an indication interrupt bit (IRQ_n) according to the level signal, and sending the instruction SerIRQ to a processor. The indication IRQ_n identifies the peripheral based on a binary code represented by a first level and a second level.
