PM_CMD_PWR—Power Management Command Power
Register
This register defines the power contribution of each command - ACT+PRE, CAS-read
and CAS write. Assumption is that the ACT is always followed by a PRE (although not
immediately), and REF commands are issued in a fixed rate and there is no need to
count them. The register has three 8-bit fields.

2.17.3
PM_BW_LIMIT_config—BW Limit Configuration Register
This register defines the BW throttling at temperature.
