Notes:
1. The symbols used for timing specifications herein follow the pattern of t
(first two letters of functional block)(signal)(state)(reference)(state)
for inputs and t
(first two letters of functional block)(reference)(state)(signal)(state)
for outputs. For example, t
PCIVKH
symbolizes 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
SYS
, reference
(K) going to the high (H) state or setup time. Also, t
PCRHFV
symbolizes PCI timing (PC) with respect to the time hard reset
(R) went high (H) relative to the frame signal (F) going to the valid (V) state.
2. See the timing measurement conditions in the
PCI 2.2 Local Bus Specifications.
3. For purposes of active/float timing measurements, the Hi-Z or off-state is defined to be when the total current delivered
through the component pin is less than or equal to the leakage current specification.
4. Input timings are measured at the pin.
5. In rev. 2.0 silicon, due to errata, t
PCIXKH
minimum is 1 ns. Refer to Errata PCI17 in
Chip Errata for the MPC8360E, Rev. 1.
