Processor Uncore Configuration Registers
13.2.1.14 MH_EXT_STAT
Capture externally asserted MEM_HOT[1:0]# assertion detection.
13.2.1.15 SMB_STAT_[0:1]
SMBus Status
This register provides the interface to the SMBus / I2C SCL and SDA signals that is 
used to access the Serial Presence Detect EEPROM (SPD) or Thermal Sensor on DIMM 
(TSOD) that defines the technology, configuration, and speed of the DIMMs controlled 
by iMC.

MH0_DIMM_ID (mh0_dimm_id):
Hottest DIMM ID for MEM_HOT[0]#. PCU microcode search the hottest 
DIMM temperature and write the hottest temperature and the 
corresponding Hottest DIMM CID/ID.
000 - DIMM0
001 - DIMM1

MH0_TEMP (mh0_temp):
Hottest DIMM Sensor Reading for MEM_HOT[0]# - This reading represents 
the temperature of the hottest DIMM. PCU microcode search the hottest 
DIMM temperature and write the hottest temperature and the 
corresponding Hottest DIMM CID/ID. Note: iMC hardware load this value 
into the MEMHOT duty cycle generator counter since PCU microcode may 
update this field at different rate/time. This field is ranged from 0 to 127, 
i.e. the most significant bit is always zero.

MH_EXT_STAT_1 (mh_ext_stat_1):
MEM_HOT[1]# assertion status at this sense period.
Set if MEM_HOT[1]# is asserted externally for this sense period, this running 
status bit will automatically updated with the next sensed value in the next 
MEM_HOT input sense phase.

status bit will automatically updated with the next sensed value in the next
