Descriptions of options
AVR® IAR C/C++ Compiler
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
N 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.
