This register allows the revision of the S/UNI-QUAD to be read by software permitting graceful migration to support newer feature enhanced versions of the S/UNI-QUAD. It also provides software reset capability.

In addition, writing to this register simultaneously loads all the performance meter registers in the RSOP, RLOP, RPOP, RXCP and TXCP blocks.

ID[2:0]:

The ID bits can be read to provide a binary S/UNI-QUAD revision number.

TYPE[3:0]:

The TYPE bits distinguish the S/UNI-QUAD from the other members of the S/UNI family of devices.

RESET:

The RESET bit allows the S/UNI-QUAD to be reset under software control. If the RESET bit is a logic one, the entire S/UNI-QUAD is held in reset. This bit is not self-clearing. Therefore, a logic zero must be written to bring the S/UNI-QUAD out of reset. Holding the S/UNI-QUAD in a reset state places it into a low power, stand-by mode. A hardware reset clears the RESET bit, thus negating the software reset. Otherwise, the effect of a software reset is equivalent to that of a hardware reset.
