I'm just made a diagnostics program that looks at the interrupt
registers to see what happens when I insert/remove the card from the
PCMCIA slot.  It does it forever in a thread. I enabled the EINT1
interrupt by setting bit 5 in the INTMR1.  The interrupts work fine
inside the CL-PS6700, and the bits in the ISR are set for that
controller.  However, I would expect bit 5 in the INTSR1 of the EP7211
to be set as well after that interrupt occurs.  Unless of course the HAL
clears this for some reason.
