DESCRIPTION
48MHz System clock while VCC5V powered
up. PECI and FAN will use this clock to drive
logics.
Over temperature alert. Low active.
BEEP output when abnormal event occurs.
When this is no abnormal events, this pin
asserts low.
Interrupt request output when abnormal
events occur.
System Management Interrupt (open drain).
