O
Attention indicators. These two outputs are provided per slot as attention indicators and can
be independently programmed to drive high, low, fast blink, and slow blink. The timer is
based on the PCI clock frequency and the state of SYSM66EN.

CBT switch control for PCI bus. This output controls the CBT switch that connects the
hot-plug slot to the system PCI bus. This output is only driven by the HPC3130 under
programmed control.

HPC3130 under programmed control.

I
Card detection signals. These two card detect input signals, DETECT0 and DETECT1, are
provided as additional card detection signals to the PRSNT1 and PRSNT2. Since only one
present input must be tied to ground to indicate a card is present per the PCI Specification
these optional inputs are provided for designers of a more mechanically robust system. If the
protection enable bit is set to 1 in the general configuration register, the HPC3130 does not
power a hot-plug slot unless DETECT0 and DETECT1 are input low. A design not
implementing additional card detection must tie these signals to ground. When this feature is
utilized, the HPC3130 guarantees that power can not be applied to an empty slot or a slot
with a partially inserted card.

I/O
PCI bus frequency indicator. This signal indicates the PCI clock frequency requirements of
the hot-plug slots and is only required in a 66-MHz system (two slot maximum electrical
loading limits). The two slot interfaces that provide the M66EN terminals are sensed at PCI
reset and are driven afterwards.

I
Present signals. These inputs are provided by hot-plug slots to indicate that an add-in card is
physically present in the slot and to power requirements to the system. Only one of these
signals must be tied to ground to indicate a card is present in an expansion slot. A set of
PRSNT1 and PRSNT2 inputs are provided for each hot-plug slot.

asserted.
