Processor Configuration Registers
2.17.2
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 3 8-bit fields.
