Notes:
1
Input specifications are measured from the TTL level (0.8 or 2.0 V) of the signal in question to the 1.4 V of the rising
edge of SYSCLK. Both input and output timings are measured at the pin (see Figure 3).
2
Processor and memory interface signals are specified from the rising edge of the 60x bus clock (which is internally
synchronized to SYSCLK).
3
Group I input signals include the following processor, L2, and memory interface signals: A[0–31], PAR[0–7]/AR[1–8],
BR[0–4], BRL2, XATS, LBCLAIM, ADS, BA0, TV and HIT (when configured for external L2)
4
Group II input signals include the following processor and memory interface signals: TBST, TT[0–4], TSIZ[0–2], WT,
CI, GBL, AACK, and TA.
5
Group III input signals include the following processor and memory interface signals: DL[0–31] and DH[0–31].
6
Group IV input signals include the following processor and L2 interface signals: TS, ARTRY, DIRTY_IN, and HIT
(when configured for internal L2 controller).
7
PCI 3.3 V signaling environment signals are measured from 1.65 V (Vdd ÷ 2) on the rising edge of SYSCLK to
V
OH
= 3.0 V or V
OL
= 0.3 V. PCI 5 V signaling environment signals are measured from 1.65 V (Vdd ÷ 2) on the rising
edge of SYSCLK to V
OH
= 2.4 V or V
OL
= 0.55 V.
8
Group V input signals include the following bussed PCI interface signals: FRAME, C/BE[0–3], AD[0–31], DEVSEL,
IRDY, TRDY, STOP, PAR, PERR, SERR, LOCK, FLSHREQ, and ISA_MASTER.
9
Group VI input signal is the point-to-point PCI GNT input signal.
10
The setup and hold time is with respect to the rising edge of HRST (see Figure 4). Mode select inputs include the
RCS0, FOE, and DBG0 configuration inputs.
11
t
sysclk
is the period of the external clock (SYSCLK) in nanoseconds (ns). When the unit is given as t
sysclk
,
the
numbers given in the table must be multiplied by the period of SYSCLK to compute the actual time duration (in
nanoseconds) of the parameter in question.
12
These values are guaranteed by design and are not tested.
