(C COMPILER PACKAGE FOR S1C33 FAMILY) (Ver. 4)
The following 20 types of pseudo-instructions are available for the Assembler as33:
Each instruction begins with a period (.).
Examples:
For details on the notation of each pseudo-instruction and its functionality, refer to Section 11.8 "Assembler
Pseudo-Instructions".
A label is an identifier designed to refer to an arbitrary address in the program. You can refer to a branch
destination of a program or an address in the CODE/DATA section by using a symbol defined as a label.
Definition of a label
A symbol described in the following format is regarded as a label.
<Symbol>:
Preceding spaces and tabs are ignored. It is a general practice to describe from the top of a line.
A defined symbol denotes the address of a described location.
An actual address value will be determined in the linking process.

A label occupies one line of a source program. An instruction described in the same line will result in an
error. However, comments may be described in the same line with a label.
The maximum number of characters of a label is 128 (not including colons).
<address>
<data 1>[,<data 2>..,<data n>] Defines half word data in the CODE/DATA section.
