Auto End of Interrupt. This feature is present, but is not recommended for use. When
set to 1, this bit causes the PIC to automatically issue an End of Interrupt internally,
immediately after each Interrupt Acknowledge from the CPU. When cleared to 0 (the
default), it requires software action (writing to the OCW2 register) to signal End of Inter-
rupt.
0: Normal EOI.
1: Auto EOI (not recommended).
Reserved. Write to 1 (8086/8088 mode).
