Interrupt Controller
Interrupt Vector Listing
PS025111-1207
Note:
The interrupt controller on the Z8 Encore!
requests from the on-chip peripherals and the GPIO port pins. The features of the 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 regarding
interrupt servicing by the eZ8 CPU, refer to eZ8 CPU User Manual (UM0128) available
for download at www.zilog.com.

with the most significant byte (MSB) at the even program memory address and the least
significant byte (LSB) at the odd program memory address.
Some port interrupts are not available on the 20-pin and 28-pin packages. The ADC
interrupt is unavailable on devices not containing an ADC.
Seventeen interrupt sources using sixteen unique interrupt vectors:
–
–
Flexible GPIO interrupts
–
–
Three levels of individually programmable interrupt priority
Watchdog Timer can be configured to generate an interrupt
Twelve GPIO port pin interrupt sources
Five on-chip peripheral interrupt sources (Comparator Output interrupt shares one
interrupt vector with PA6)
Eight selectable rising and falling edge GPIO interrupts
Four dual-edge interrupts
lists the interrupts available in order of priority. The interrupt vector is stored
