4.16.1 Interrupt Types
Table 14 presents interrupt names, types, vector table address, End-of-Interrupt (EOI) type,
overall priority, and related instructions.
Table 14. Interrupt Types
Note: If the priority levels are not changed, the default priority level will be used for the interrupt sources.
a
b
c
d
timers have an interrupt priority order among themselves (2A > 2B > 2C).
e
f
Not available in slave mode.
An ESC opcode causes a trap.
Instruction execution generates interrupts.
Performed in the same manner as for the 8086 and 8088.
Because only one IRQ is generated for the three timers, they share priority level with other sources. The
These interrupt types are programmable in slave mode.
