The macros in this module provide a C language interface to the
|
||
|
|
bootloader support functionality of certain AVR processors. These
|
||
|
|
macros are designed to work with all sizes of flash memory.
|
||
|
|
|
||
|
|
\note Not all AVR processors provide bootloader support. See your
|
||
|
|
processor datasheet to see if it provides bootloader support.
|
||
|
|
|
||
|
|
\todo From email with Marek: On smaller devices (all except ATmega64/128),
|
||
|
|
__SPM_REG is in the I/O space, accessible with the shorter "in" and "out"
|
||
|
|
instructions - since the boot loader has a limited size, this could be an
|
||
|
|
important optimization.
