ADDR0 ->
ADDR1 ->
PMB_DATA ->
PMB_CLK ->
SMB_ALRT ->

You can connect all of these to GND at Thermal pad if not used. Same applies to only SMB_ALRT

Hi Mathew-san,

Thank you for your reply.
Just to be sure please let me check about pin connection.
Is there any problem if the SMBALERT pin is floating when SMBALERT is not used?
