Register 0000H: S/UNI-2488 Identity and Global Performance Monitor Update
This register allows the revision number of the S/UNI-2488 to be read by software permitting
graceful migration to newer, feature-enhanced versions of the S/UNI-2488.
In addition, writing to the S/UNI-2488 Identity and Global Performance Monitor Update register
(0000H) performs a global performance monitor update by simultaneously loading all the
performance meter registers in the RHPP, RRMP, RCFP, RXSDQ, SVCA, PRGM, TXSDQ,
TCFP, R8TD, and T8TE blocks.

The ID bits can be read to provide a binary S/UNI-2488 revision number. A value of 0x0
means the device is a revision A S/UNI-2488. A value of 0x1 means the device is a revision
B S/UNI-2488. A value of 0x2 means the device is a revision C S/UNI-2488. A value of 0x3
means the device is a revision D S/UNI-2488.
The TYPE bits can be read to distinguish the S/UNI-2488 from the other members of the
S/UNI family of devices. The TYPE[4:0] register for the PM5381 S/UNI-2488 is 00010.
