S3C72M5/C72M7/C72M9/P72M9 (Preliminary Spec)
7
OVERVIEW
The S3C72M5/C72M7/C72M9 interrupt control circuit has five functional components:
— Interrupt enable flags (IEx)
— Interrupt request flags (IRQx)
— Interrupt master enable register (IME)
— Interrupt priority register (IPR)
— Power-down release signal circuit
Three kinds of interrupts are supported:
— Internal interrupts generated by on-chip processes
— External interrupts generated by external peripheral devices
— Quasi-interrupts used for edge detection and as clock sources
