Description
Assigns or reassigns a value to a symbol. This directive is used to
create and manipulate assemble-time variables.
Defines a run-time breakpoint.
Specifies that the following instructions should be, or should not be,
case sensitive.
Sets SX device options. These directives usually precede all other direc-
tives and instructions.
Increments the memory pointer ($) by value. Used to reserve RAM and
E
Defines words in EEPROM.
Marks the end of the source code. All text following the END will be
ignored by the assembler.
Assigns a value to a symbol. This directive is used to create assemble-
time variables.
Defines an assemble-time error or warning.
Specifies that the following macro instructions should be, or should not
be, expanded in the list file. (See section 7.4.5 – The EXPAND and
NOEXPAND Directives for a detailed description.)
Specifies the clock frequency, in Hz, to be generated by the SX-Key
during debugging.
Defines FUSE and FUSEX words as explicit expression values. Not
recommended for use.
Assigns a value to the 8-byte ID word in the SX. The text argument
may be up to 8 characters and should be enclosed in apostrophes.
Conditional assembly and alternate conditional assembly block.
Conditional assembly and alternate conditional assembly block based
upon symbol definitions.
Includes a source code file, i.e. the INCLUDE directive is replaced by
the contents of the file specified with the directive.
Specifies the calibration value for the internal RC oscillator.
Controls the list format, and sets certain options
Declares the labels named after the directive as private symbols that
are only available inside a macro body. (See section 7.4.4 – The LOCAL
directive for a detailed description.)
Inserts a form feed at this point in the list file.
Defines a macro. (See section 7.4 – Macros for a detailed description.)
