Document Conventions
Throughout this data manual, several conventions are used to convey information. These conventions are
listed below:
1. To identify a binary number or field, a lower case b follows the numbers. For example: 000b is a 3-bit binary
2. To identify a hexadecimal number or field, a lower case h follows the numbers. For example: 8AFh is a
3. All other numbers that appear in this document that do not have either a b or h following the number are
4. If the signal or terminal name has a bar above the name (for example, GRST), then this indicates the
5. Differential signal names end with P, N, +, or − designators. The P or + designators signify the positive
6. RSVD indicates that the referenced item is reserved.
7. The power and ground signals in Figure 2−1 are not subscripted to aid in readability.
8. In Sections 4 through 6, the configuration space for the bridge is defined. For each register bit, the software
