Descriptions of options

Reference Guide

--eec++

--eec++

In the AVR IAR C/C++ Compiler, the default language is C. If you take advantage of 
Extended Embedded C++ features like namespaces or the standard template library in 
your source code, you must use this option to set the language the compiler uses to 
Extended Embedded C++. See IAR Extended Embedded C++, page 110.

To set the equivalent option in IAR Embedded Workbench, select 
Project>Options>C/C++ Compiler>Language.

--eecr_address

--eecr_address address

If you use the 

-v

 processor option, the 

--eecr_address

 option can be used for 

modifying the value of the 

EECR

 address, where 

0x1C

 is the default.

If you use the 

--cpu

 processor option, the 

--eecr_address

 option is implicitly set, 

which means you should not use these options together.

--enable_multibytes

--enable_multibytes 

By default, multibyte characters cannot be used in C or C++ source code. If you use this 
option, multibyte characters in the source code are interpreted according to the host 
computer’s default setting for multibyte support.

Multibyte characters are allowed in C and C++ style comments, in string literals, and in 
character constants. They are transferred untouched to the generated code.

To set the equivalent option in IAR Embedded Workbench, choose 
Project>Options>C/C++ Compiler>Language.

--eeprom_size

--eeprom_size=N

Use this option to enable the 

_ _eeprom

 extended keyword by specifying the size of the 

built-in EEPROM. The value 

 can be 

0–65536

. 

Note: To use the 

_ _eeprom

 extended keyword, the language extensions must be 

enabled. For additional information, see -e, page 179, and #pragma language, page 220.

This option is related to the Code options in the C/C++ Compiler category in IAR 
Embedded Workbench.
