4.2.2 HARDWARE MONITORING BLOCK PINS

The following pins require external pullup resistors to 3.3V only:

ƒ SCLK

ƒ SDA

ƒ A0/RESET#/THERM#/XNOR_OUT if the RESET# or THERM# function is used. This limits the SMBus address

to 0101101 (unless external circuitry is provided). See section 7.18.2 SMBus Interface.

ƒ VID0-VID3

ƒ 12V_IN/VID4 if VID4 function is used.
