SDQRST:
This bit is used to reset the RXSDQ. The RXSDQ comes up in reset. It should be taken out
of reset by writing a 0 to this bit. The user can reset the SDQ at any time by writing a 1 to this
bit, and then writing a 0. Reset flushes all the data in the FIFOs, resets the read and write
pointers and resets all counters. The configuration information is not changed by Reset.
RXSDQTIP:
The RXSDQTIP bit indicates that the RXSDQ counters are in the process of being transferred
to their holding registers. A transfer is initialized by writing to the S/UNI-2488 Identity, and
Global Performance Monitor Update register (0000H).
