exception interrupts (plus reset), and 16 traps. The maskable event
interrupts share a global interrupt disable bit (the EA bit in the IEL
register) and each also has a separate individual interrupt enable bit
(in the IEL or IEH registers). Only three bits of the IPA register
values are used on the XA-S3. Each event interrupt can be set to
occur at one of 8 priority levels via bits in the Interrupt Priority (IP)
registers, IPA0 through IPA5. The value 0 in the IPA field gives the
interrupt priority 0, in effect disabling the interrupt. A value of 1 gives
the interrupt a priority of 9, the value 2 gives priority 10, etc. The
result is the same as if all four bits were used and the top bit set for
all values except 0. Details of the priority scheme may be found in
the XA User Guide .
The complete interrupt vector list for the XA-S3, including all
4 interrupt types, is shown in the following tables. The tables include
the address of the vector for each interrupt, the related priority
register bits (if any), and the arbitration ranking for that interrupt
source. The arbitration ranking determines the order in which
interrupts are processed if more than one interrupt of the same
priority occurs simultaneously.
