10 Device and Documentation Support

10.1 Documents 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

field.

2. To identify a hexadecimal number or field, a lower case h follows the numbers. For example: 8AFh is a 12-bit

hexadecimal field.

3. All other numbers that appear in this document that do not have either a b or h following the number are

assumed to be decimal format.

4. If the signal or terminal name has a bar above the name (for example, GRST), then this indicates the logical

NOT function. When asserted, this signal is a logic low, 0, or 0b.

5. Differential signal names end with P, N, +, or – designators. The P or + designators signify the positive signal

associated with the differential pair. The N or – designators signify the negative signal associated with the

differential pair.

6. RSVD indicates that the referenced item is reserved.

7. In Sections 4 through 6, the configuration space for the bridge is defined. For each register bit, the software

access method is identified in an access column. The legend for this access column includes the following

entries:

• r – read access by software

• u – updates by the bridge internal hardware

• w – write access by software

• c – clear an asserted bit with a write-back of 1b by software. Write of zero to the field has no effect

• s – the field may be set by a write of one. Write of zero to the field has no effect

• na – not accessible or not applicable
