This chapter provides an easy reference for locating instructions by their
operational codes.
Sample Program Listing
A sample program shows how the instructions, using many of the avail-
able memory modes, will translate into object code after assembly.
Manual Conventions
The following assumptions and conventions are adopted to provide clarity
and ease of use:
Courier Typeface
Commands, code lines and fragments, bits, equations, hexadecimal
addresses, and various executable items are distinguished from general
text by the use of the
Courier
typeface. Where the use of the font is not
indicated, as in the Index, the name of the entity is presented in upper
case.
•
Example: FLAGS[1] is
smrf
.
Hexadecimal Values
Hexadecimal values are designated by lowercase
h
and appear in the
Courier
typeface.
•
Example: R1 is set to
F8h
.
Brackets
The square brackets, [ ], indicate a register or bus.
•
Example: for the register R1[7:0], R1 is an 8-bit register, R1[7] is the
most significant bit, and R1[0] is the least significant bit.
