Table 61. Interrupt Types, Sources, and Vectors
When more than one interrupt is pending, priorities are resolved by a programmable
priority encoder controlled by the
activates when an interrupt request is granted. As a result, all subsequent interrupts are
disabled, and the Program Counter and Status Flags are saved. The cycle then branches to
the Program Memory vector location reserved for that interrupt.
All ZLF645 MCU interrupts are vectored through locations in the Program Memory. This
memory location and the next byte contain the 16-bit address of the interrupt service
routine for that particular interrupt request. To accommodate polled interrupt systems,
interrupt inputs are masked, and the
which of the interrupt requests require service.
An interrupt resulting from AN1 is mapped into IRQ2, and an interrupt from AN2 is
mapped into IRQ0. Interrupts IRQ2 and IRQ0 can be rising, falling, or both edge
triggered. These interrupts are user-programmable. The software can poll to identify the
state of the pin.
