Input leakage currents include hi-Z output leakage for all bidirectional buffers with three-state outputs.
Signals without pullup resistors must have 3 mA low output current. Signals requiring pullup must have 6 mA; the latter
include FRAME*, TRDY*, IRDY*, DEVSEL*, STOP*, SERR*, and PERR*.
Lower capacitance on this input-only pin allows for non-resistive coupling to AD[xx].

Timing and Switching Specifications
Overview
Host Interface (PCI) Timing and Switching Characteristics
This section defines the timing and switching characteristics of CX28560. The major
subsystems include the Host interface, the expansion bus interface, the POS-PHY
interface and the serial interface. The Host interface is Peripheral Component
Interface (PCI) compliant. For other references to PCI, see the PCI Local Bus
Specification, Revision 2.2, December 18, 1998. The POS-PHY interface is compliant
to the Frame-based ATM Interface (Level 3). For other references see ATM Forum
Technical Committee document AF-PHY-0143.000, March 2000. The expansion bus
and serial bus interfaces are similar to the Host interface timing characteristics; the
differences and specific characteristics common to either interface are further defined.
Reference the PCI Local Bus Specification, Revision 2.2, December 18, 1998 for
information the following:
Parameter
• Indeterminate inputs and metastability
• Power requirements, sequencing, and decoupling
• PCI DC specifications
• PCI AC specifications
• PCI V/I curves
• Maximum AC ratings and device protection
