3.1.2.2 60x Bus Input AC Specications
Table 8 provides the 60X bus input AC timing specications for the PPC740 and
PPC750 as dened in Figure 3 and Figure 4 . Input timing specications for the L2 bus are
Notes:
1. Input specications are measured from the TTL level (0.8 to 2.0 V) of the signal in question to the 1.4V
of the rising edge of the input SYSCLK. Input and output timings are measured at the pin (see
2. Address/Data Transfer Attribute inputs are composed of the following--A[0-31], AP[0-3], TT[0-4],TBST,
TSIZ[0-2], GBL, DH[0-31), DL[0-31], DP[0-7].
3. All other signal inputs are composed of the following--TS, ABB, DBB, ARTRY, BG, AACK, DBG,
DBWO, TA, DRTRY, TEA, DBDIS, TBEN, QACK, TLBISYNC.
4. The setup and hold time is with respect to the rising edge of HRESET (see Figure 4 ).
5. tsysclk, is the period of the external clock (SYSCLK) in nanoseconds (ns). The numbers given in the
table must be multiplied by the period of SYSCLK to compute the actual time duration (in ns) of the
parameter in question.
6. These values are guaranteed by design, and are not tested.
7. This specication is for conguration mode select only. Also note that the HRESET must be held
asserted for a minimum of 255 bus clocks after the PLL re-lock time during the power-on reset
sequence.
