This register was previously named TCPPIEOIR, and that name will continue to exist in the
CSL for backward compatibility.

End of Interrupt Vector

This is an application specific register which is essentially a general purpose output from the LCSAR.
One cycle after this register is written, the eoi_vector[7:0] value will appear on the eoi_vector output port
from the LCSAR and the eoi_write output port will be asserted for 1 clock cycle. This register is used to
convert level sensitive interrupts to pulsed, non-redundant interrupts. Software should write all zeros for
the vector value.
