8.16 Diode Selection Register -- Index 59h (Bank 0)
Reset Condition: Resume Reset, INIT.
CR59h Thermal Diode Select
K8 and NV34 GPU table is also supported in W83792D. VTIN2, VTIN3 should be always in the same
mode since they will decide the VID mapping. There is only one exception, that is, thermistor mode.
VTIN2 and VTIN3 can choose one in thermistor mode and another in other modes.
VTIN1 is separately set up in this configuration.
Configuration these bits have priority as…
Thermistor mode > K8 diode mode > NVIDIA diode mode > P4 mode.
