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 1111 is a binary number. In some
cases, the letter B is added for clarity.)
Units of Measure The following abbreviations are used to represent units of
measure:
A amps, amperes
GByte gigabytes
KByte kilobytes
KΩ kilo-ohms
mA milliamps, milliamperes
MByte megabytes
MHz megahertz
ms milliseconds
mW milliwatts
ns nanoseconds
pF picofarads
W watts
V volts
µA microamps, microamperes
µF microfarads
µs microseconds
µW microwatts
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).
