Interrupt Controller
PS022008-0810
The interrupt controller on the ZNEO
from on-chip peripherals and the GPIO port pins. The features of the interrupt controller
includes:
•
•
•
The IRQs allow peripheral devices to suspend CPU operation in an orderly manner and
force the CPU to start an ISR. Usually this service routine is involved with exchange of
data, status information, or control information between the CPU and the interrupting
peripheral. When the service routine is completed, the CPU returns to the operation from
which it was interrupted.
System exceptions are non-maskable requests which allow critical system functions to
suspend CPU operation in an orderly manner and force the CPU to start a service routine.
Usually this service routine tries to determine how critical the exception is. When the
service routine is complete, the CPU returns to the operation from which it was
interrupted.
The ZNEO Z16F Series supports both vectored and polled interrupt handling. For polled
interrupts, the interrupt control has no effect on operation. For more information on
interrupt servicing by the ZNEO CPU, refer to the ZNEO CPU User Manual available for
download at www.zilog.com.
Flexible GPIO interrupts:
– Eight selectable rising and falling edge GPIO interrupts
– Four dual-edge interrupts
Three levels of individually programmable interrupt priority
