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.
|
||||
|
||||
Global interrupts are not automatically disabled for these macros. It
|
||||
is left up to the programmer to do this. See the code example below.
|
||||
Also see the processor datasheet for caveats on having global interrupts
|
||||
enabled during writing of the Flash.
|
||||
|
||||
\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.
|
||||
|
||||

|
||||
}
|
||||
|
||||
boot_page_write (page); // Store buffer in flash page.
|
