The register is used to access the registers located in the H/W Monitoring
Register block. The value in this register is the register INDEX (address),
which determines the register currently accessible.
This register is used to Read/Write the data in the hardware monitoring
register that is currently INDEX’d. (See the HW_Reg INDEX register at
offset 60h.)
