9.1.1 Third-Party Products Disclaimer

TI'S PUBLICATION OF INFORMATION REGARDING THIRD-PARTY PRODUCTS OR SERVICES DOES NOT

CONSTITUTE AN ENDORSEMENT REGARDING THE SUITABILITY OF SUCH PRODUCTS OR SERVICES

OR A WARRANTY, REPRESENTATION OR ENDORSEMENT OF SUCH PRODUCTS OR SERVICES, EITHER

ALONE OR IN COMBINATION WITH ANY TI PRODUCT OR SERVICE.

9.1.2 Device Nomenclature

Throughout this data sheet, several conventions are used to convey information. A list of these conventions are

as follows:

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. For each register bit in Register Maps, 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 host controller 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
