24 | Legal values are in the range of 0-31. Bit 0 maps to | ||

26 | enables the thermal input of that particular UCH and | ||
27 | setting a bit to 0 enables the voltage input. | ||
28 | |||
29 | * int_mode: int Override the BIOS default temperature interrupt mode. | ||
30 | The only possible value is 0 which forces interrupt | ||
31 | mode 0. In this mode, any pending interrupt is cleared | ||
