15 PCI

This section describes the DC and AC electrical specifications for the PCI bus of the MPC8533E.

15.1

PCI DC Electrical Characteristics

Table 50 provides the DC electrical characteristics for the PCI interface.

15.2

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 51 provides the PCI AC timing specifications at 66 MHz.
