13.2
This section describes the general AC timing parameters of the PCI bus of the MPC8347EA. Note that the
PCI_CLK or PCI_SYNC_IN signal is used as the PCI input clock depending on whether the MPC8347EA
is configured as a host or agent device.

Notes:
1. The symbols for timing specifications follow the pattern of t
2. See the timing measurement conditions in the PCI 2.3 Local Bus Specifications.
3. For active/float timing measurements, the Hi-Z or off state is defined to be when the total current delivered through
4. Input timings are measured at the pin.
6. PCI timing depends on M66EN and the ratio between PCI1/PCI2. Refer to the PCI chapter of the reference manual
for inputs and t
PCI timing (PC) with respect to the time the input signals (I) reach the valid state (V) relative to the PCI_SYNC_IN
clock, t
respect to the time hard reset (R) went high (H) relative to the frame signal (F) going to the valid (V) state.
