Note: If the priority levels are not changed, the default priority level will be used for the interrupt sources.
a_{Instruction execution generates interrupts.}
b_{Performed in the same manner as for the 8086 and 8088.}
c_{An ESC opcode causes a trap.}
d_{Because only one IRQ is generated for the three timers, they share priority level with other sources. The}
timers have an interrupt priority order among themselves (2A > 2B > 2C).
e_{These interrupt types are programmable in slave mode.}
f_{Not available in slave mode.}
