Pin 3 of W83793G is a multi-function pin. It can be the IRQ output or the SMI# output signal. The
function is selected by programming Bank0 CR50 SMI/IRQ Control register.
The interrupt mode for voltage and FANIN is only two-time interrupt mode.
For temperature, there are three modes to serve: <1> Comparator mode, <2>One-Time Interrupt
mode, and <3> Two-Time Interrupt mode.
8.5.2 INT/SMI Control/Status Register Details
8.5.2.1 Interrupt Status Register (INT_STS)
A one represents corresponding channel have been exceed its limit. Read Interrupt Status will clear
the interrupt flag.
VIDCHG will assert while VID are on the fly. It indicates VID have change in last 1ms.
TART will assert while target temperature cannot be achieved after 3 minutes full speed of
corresponding FAN.
