level, then it is up to the interrupt service routine to determine the correct
source of the interrupt.
If the AE bit is 0, then each interrupt request is presented with a vector
number. The low five bits of the vector number (4–0) are determined
based on the highest pending priority, with active fast interrupts having
priority over active normal interrupts. The remaining two bits (vector bits
5 and 6) are determined based on whether the interrupt request is a fast
interrupt and the setting of the FVE bit. If FVE is set, then a fast interrupt
request has a vector number different from that of a normal interrupt
request as shown in
If FVE is 0, both normal and fast interrupts have the same vector and
requests assigned to priority levels 0–31 are mapped to vector numbers
32–63 in the vector table.
If FVE is 1, normal interrupt requests assigned to priority levels 0–31 are
mapped to vector numbers 32–63 and fast interrupt requests assigned
to priority levels 0–31 are mapped to vector numbers 64–95 in the vector
table. See
