Interrupt Controller
Interrupt Vector Listing

Note:
The interrupt controller on the Z8 Encore! XP
interrupt requests from the on-chip peripherals and the GPIO port pins. The features of
interrupt controller include:
•
•
•
•
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
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.
The eZ8 CPU supports both vectored and polled interrupt handling. For polled interrupts,
the interrupt controller has no effect on operation. For more information on interrupt
servicing by the eZ8 CPU, refer to eZ8 CPU Core User Manual (UM0128) available for
download at www.zilog.com.

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.
