This register allows the revision of the S/UNI-PLUS to be read by software

permitting graceful migration to newer, feature enhanced versions of the

S/UNI-PLUS.

ID[2:0]:

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

TIP:

The TIP bit is set to a logic one when any value is written to this register.

Such a write initiates an accumulation interval transfer and loads all the

performance meter registers in the RSOP, RLOP, RPOP, RACP, and TACP

blocks. TIP remains high while the transfer is in progress, and is set to a logic

zero when the transfer is complete. TIP can be polled by a microprocessor to

determine when the accumulation interval transfer is complete.

TYPE[2:0]:

The TYPE bits can be read to distinguish the S/UNI-PLUS from the other

members of the S/UNI family of devices.

RESET:

The RESET bit allows the S/UNI-PLUS to be reset under software control. If

the RESET bit is a logic one, the entire S/UNI-PLUS is held in reset. This bit

is not self-clearing; therefore, a logic zero must be written to bring the
