1.2.5 Notations and Conventions

External signals:

Active-low mark [1]:

Capital letters (e.g., IDSEL)

Overbar (e.g., DEVSEL)

Internal function units: capital (non-bold) letters (e.g., VFE)

Buses:

XXmsb_index..lsb_index (e.g., AD31..0)

Register fields:

XXmsb_index:lsb_index (e.g., Mode27:16)

Register types:

R - read only

RC - read-clear. Writing ‘1’ clears the register bit.

RS - read-set. Writing ‘1’ sets the register bit to ‘1’.

RW - read-write (contents of write can be read back)

W - write only (contents of read are meaningless)

Numbers:

Unmarked numbers are decimal (e.g., 365, 23.19). Hexadecimal numbers are marked with a ‘0x’ prefix (e.g., 0xB000,

0x3). Binary numbers are marked with a ‘b’ suffix (e.g., 010b, 0000110100011b).

1. In this document, an overbar is used to denote active low signals. In other documents referenced herein, such as the PCI specifications, the # suffix notation is often

used instead. The two forms of notation are interchangeable. Thus, for example, DEVSEL is equivalent to DEVSEL#.
