Actually, I don't know.  I don't have an LPC to work with and could not
find the info in the docs either.  I have been doing ARM development
for a while and the "trick" with the FIQ is well known.  In your case
however, it might require the use of an inverter.

Bill,

A good thought.  But isn't EINTx active low?  I need to detect low to
high.

  Try connecting the READY line to an EINT pin configured as the ONLY
FIQ interrupt, then place the ACTUAL code for the FIQ service routine
(not the LDR PC,... instruction) in RAM at 0x001C.
