I only use the lower part to count 10 millisecond timer interrupts, and as long as I know where it wraps around, it should be fine. As long as there are timebase compare registers that interrupt when a match occurs on either upper or lower, we are all set. Different register numbers are OK because all get/set operations are implementation defined functions. -- Dan [[ This message was sent via the linuxppc-dev mailing list.
