The FSB Characteristics
Uses the Pentium® 4 FSB Protocol
The FSB uses the same protocol as the Pentium® 4 processor family. The BCLK speed is 100MHz (rather than 200MHz as on the Pentium® 4). The address bus width is 32 bits consisting of A[31:3]# (rather than 36 bits as on the Pentium® 4's FSB).
Pentium® M-Specific Signals
The signals in Table 58-1 on page 1428 are specific to the Pentium® M processor (i.e., they are not found on the Pentium® 4 family processors).
| Signal | Input/Output | Description |
