General Purpose Input Pins
The general purpose input (GPI) pins can be connected to any 3.3-V digital signal for read-back to the system
controller. These inputs are switch de-bounced for direct connection to a VAUXA/B control (switch), attention or
manually-operated retention latch. Each GPI pin has an internal 100-k
pull down.
Poweroff
The PWROFFA/B bits are available through the SMBus function register. PWROFF is a logic 1 when the slot
main power and VAUX are less than the low comparitor threshold (100 mV typ). It can be used to determine that
the slot is off and it is safe to remove or install a module in the slot.
