Name Bit(s) Type Function

HWREV

<31:24> R/W, 0 Hardware Revision. Identifies the hardware

revision level of a TLSB node. The value will be

loaded by hardware or self-test firmware during

node self-test. Bits <31:28> specify a major revi-

sion number and bits <27:24> specify a minor re-

vision number to be displayed by the console in

the format 0.0 through 15.15.

SWREV

<23:16> R/W, 0 Software Revision. Identifies the software (or

firmware) revision level of a TLSB node. The

value will be loaded by hardware or self-test

firmware during node self-test. Bits <23:20>

specify a major revision number and bits

<19:16> specify a minor revision number to be

displayed by the console in the format 0.0

through 15.15. These bits shall be zero if a soft-

ware revision level is not applicable to this node.
