NOTE
Notes provide information and may be used to emphasize a recommended
sequence of steps.
<F1> A letter, number, symbol, or word enclosed in < > represents a key on your keyboard.
For example, the instruction "press <F1>" means press the key labeled "F1" on your
keyboard.
<Enter> The <Enter> key is used to enter commands and responses to prompts. Some manuals
refer to <Enter> as RETURN, CARRIAGE RETURN, <CR>, or use an arrow. All of
these terms are interchangeable.
<x + y> Two or three key names, separated by plus signs, indicate multiple-key entries. For
example, <Ctrl + Alt + Del> means hold down <Ctrl> and <Alt> and press <Del>.
_L In all tables in this guide, active-low signal names have an “_L” symbol following the
name; for example, DSTBN3_L. Active-high signal names do not have a “_L” suffix.
