Configuration parameters, function names, path names and file names are written in italic typeface.
Example: dev_id
Source code examples are given in a small, fixed-width typeface.
Example:
int a = 10;
Menus and commands from menus and submenus are enclosed in double-quotes. Example:
Create a new project using the "Create Project..." command from the "File" menu.
The members of a bit field or a group of signals are numbered starting at zero, which is the least
significant bit.
Example: CFG[4:0] identifies a group of five signals, where CFG0 is the least significant bit and
CFG4 is the most significant bit.
If necessary, numbers are represented with a suffix that specifies their base.
Example: 12AB16 is a hexadecimal number (base 16 = hexadecimal) and is equal to 477910.
The bit fields of a register are displayed with the most significant bit to the left. Below each bit field
is a description of its read / write accessibility and its default value:
15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0
A B C D E F G H I J K L N O

legend:
r bit is readable
rc this bit is cleared after a read
r,w bit is readable and writeable, reading yields the previously written value unless otherwise
specified.
w bit is writeable, read value is undefined
wc writing a 1 to this bit clears it
w,0 bit is write-only, reading always yields 0.
0 default value
