Pentium
III Processor for the SC242 at 450 MHz to 1.0 GHz
Note:
For

Figure 13
, the following apply:
1.
Figure 7
through
Figure 13
are to be used in conjunction with
Table 12
through
Table 18
.
2. All AC timings for the AGTL+ signals at the processor core pins are referenced to the BCLK
rising edge at 1.25 V. All AGTL+ signal timings (address bus, data bus, etc.) are referenced at
1.00 V at the processor core pins.
