Notation Definition
# The pound symbol (#) appended to a signal name indicates that the signal
is active low. (e.g., PM_BMBUSY#)
Variables Variables are shown in italics. Variables must be replaced with correct
values.
Instructions Instruction mnemonics are shown in uppercase. When you are
programming, instructions are not case-sensitive. You may use either
uppercase or lowercase.
Numbers Hexadecimal numbers are represented by a string of hexadecimal digits
followed by the character H. A zero prefix is added to numbers that begin
with A through F. (For example, FF is shown as 0FFH.) Decimal and binary
numbers are represented by their customary notations. (That is, 255 is a
decimal number and 1111 is a binary number. In some cases, the letter B
is added for clarity.)

Signal Names Signal names are shown in uppercase. When several signals share a
common name, an individual signal is represented by the signal name
followed by a number, while the group is represented by the signal name
followed by a variable (n). For example, the lower chip-select signals are
named CS0#, CS1#, CS2#, and so on; they are collectively called CSn#.
A pound symbol (#) appended to a signal name identifies an active-low
signal. Port pins are represented by the port abbreviation, a period, and
the pin number (e.g., P1.0).
