2.3 Document's 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 Section 4 through Section 6, the configuration space for the host controller 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 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
