This register allows the revision number of the S/UNI-622-MAX to be read by software permitting
graceful migration to newer, feature-enhanced versions of the S/UNI-622-MAX.
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-622-MAX revision number.
TYPE[3:0]:
The TYPE bits can be read to distinguish the S/UNI-622-MAX from the other members of the
S/UNI family of devices.
RESET:
The RESET bit allows the S/UNI-622-MAX to be reset under software control. If the RESET
bit is a logic one, the entire S/UNI-622-MAX is held in reset. This bit is not self-clearing.
Therefore, a logic zero must be written to bring the S/UNI-622-MAX out of reset. Holding the
S/UNI-622-MAX 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.
