Interrupt Controller
Overview

PS025203-0405
Note:
The interrupt controller on the Z8 Encore!
rupt requests from the on-chip peripherals and the GPIO port pins. The features of the
interrupt controller include the following:
•
•
•
•
Interrupt requests (IRQs) allow peripheral devices to suspend CPU operation in an orderly
manner and force the CPU to start an interrupt service routine (ISR). Usually this interrupt
service routine is involved with the exchange of data, status information, or control infor-
mation between the CPU and the interrupting peripheral. When the service routine is com-
pleted, the CPU returns to the operation from which it was interrupted.
The eZ8 CPU supports both vectored and polled interrupt handling. For polled interrupts,
the interrupt controller has no effect on operation. Refer to the eZ8 CPU User Manual for
more information regarding interrupt servicing by the eZ8 CPU. The eZ8 CPU User Man-
ual is available for download at www.zilog.com.
Table 33 lists all of the interrupts available in order of priority. The interrupt vector is
stored with the most significant byte (MSB) at the even Program Memory address and the
least significant byte (LSB) at the following odd Program Memory address.
Some port interrupts are not available on the 8- and 20-pin packages. The ADC interrupt is
unavailable on devices not containing an ADC.
20 unique interrupt vectors:
–
