Structure of Interrupt Vector
In case more than one source is active, the generated vector refers to the active group
with highest priority (group 1 has highest, group 8 lowest priority).
Interrupt groups 1 to 6 are assigned to definite single interrupt indications. These are
urgent receive and transmit interrupts which need to be serviced quickly. Due to this, no
read access to Interrupt Status Registers is necessary: the corresponding interrupt
indication is reset after the INTA cycle has been finished. Groups 7 and 8 combine all
other interrupt sources. Thus, the same procedure as described for Interrupt Polling has
to be used.
An interrupt of the Universal Port can be included in both the interrupt group 7 and the
interrupt group 8. If triggered solely, it is assigned to group 7.
With the exception of daisy chaining mode where IE1 input directly influences INT pin
activation/deactivation the INT signal is reset when all interrupt indications are cleared
(acknowledged).
