64-bit Counter Lower
These bits are the least significant bits of the 64-bit counter. The 64-bit counter can be used to
count events on the VMEbus IRQ[1]I_ or IRQ[2]I_ signal lines. Since the 64-bit counter is
comprised of two 32-bit registers, it is possible that the lower counter may roll over between a
read or write of the upper and lower portions. Software must consider this case.
