KS32C50100 RISC MICROCONTROLLER INTERRUPT CONTROLLER - - - INTERRUPT CONTROLLER The KS32C50100 interrupt controller has a total of 21 interrupt sources. Interrupt requests can be generated by internal function blocks and at external pins. The ARM7TDMI core recongnizes two kinds of interrupts: a normal interrupt request (IRQ), and a fast interrupt request (FIQ). Therefore all KS32C50100 interrupts can be categorized as either IRQ or FIQ. The KS32C50100 interrupt controller has an interrupt pending bit for each interrupt source. Four special registers are used to control interrupt generation and handling: Interrupt priority registers. The index number of each interrupt source is...
