|

|

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.
|
||||
|
||||

}

This is an adapted version which has been tested
|
||||
with the ATmega16 but should work with the ATmega8,
|
||||
ATmega169 and ATmega32. The bootloader uses block/
|
||||
page write for flash and is fast.
