<a name="l00051"></a>00051 <span class="comment"> data stored in program space (flash memory) of the device. In order to</span>
<a name="l00052"></a>00052 <span class="comment"> use these functions, the target device must support either the \c LPM or</span>
<a name="l00053"></a>00053 <span class="comment"> \c ELPM instructions.</span>
<a name="l00054"></a>00054 <span class="comment"></span>
<a name="l00055"></a>00055 <span class="comment"> \note These functions are an attempt to provide some compatibility with</span>
<a name="l00056"></a>00056 <span class="comment"> header files that come with IAR C, to make porting applications between</span>
<a name="l00057"></a>00057 <span class="comment"> different compilers easier. This is not 100% compatibility though (GCC</span>
<a name="l00058"></a>00058 <span class="comment"> does not have full support for multiple address spaces yet).</span>
<a name="l00059"></a>00059 <span class="comment"></span>
<a name="l00060"></a>00060 <span class="comment"> \note If you are working with strings which are completely based in ram,</span>
<a name="l00061"></a>00061 <span class="comment"> use the standard string functions described in \ref avr_string.</span>
<a name="l00062"></a>00062 <span class="comment"></span>
<a name="l00063"></a>00063 <span class="comment"> \note If possible, put your constant tables in the lower 64 KB and use</span>
<a name="l00064"></a>00064 <span class="comment"> pgm_read_byte_near() or pgm_read_word_near() instead of</span>
<a name="l00065"></a>00065 <span class="comment"> pgm_read_byte_far() or pgm_read_word_far() since it is more efficient that</span>
<a name="l00066"></a>00066 <span class="comment"> way, and you can still use the upper 64K for executable code.</span>
<a name="l00067"></a>00067 <span class="comment"> All functions that are suffixed with a \c _P \e require their</span>
<a name="l00068"></a>00068 <span class="comment"> arguments to be in the lower 64 KB of the flash ROM, as they do</span>
<a name="l00069"></a>00069 <span class="comment"> not use ELPM instructions. This is normally not a big concern as</span>
<a name="l00070"></a>00070 <span class="comment"> the linker setup arranges any program space constants declared</span>
<a name="l00071"></a>00071 <span class="comment"> using the macros from this header file so they are placed right after</span>
<a name="l00072"></a>00072 <span class="comment"> the interrupt vectors, and in front of any executable code. However,</span>
<a name="l00073"></a>00073 <span class="comment"> it can become a problem if there are too many of these constants, or</span>
<a name="l00074"></a>00074 <span class="comment"> for bootloaders on devices with more than 64 KB of ROM.</span>
<a name="l00075"></a>00075 <span class="comment"> <em>All these functions will not work in that situation.</em></span>
