PCI Interface

This section describes the DC and AC electrical specifications for the PCI bus interface.

2.16.1

PCI DC Electrical Characteristics

Table 45 provides the DC electrical characteristics for the PCI interface.

2.16.2

PCI AC Electrical Specifications

This section describes the general AC timing parameters of the PCI bus. Note that the SYSCLK signal is used as the PCI input

clock. Table 46 provides the PCI AC timing specifications at 66 MHz.
