13 /*
14 * spminterface.h offers a lightweight interface by inserting
15 * an small machine-subroutine into the bootsection. (right
16 * after the interrupt-vector-table)
17 * This subroutine can be called by normal code in order to
18 * enable it to program the flash (and depending on BLB11-lockbit
19 * also the bootsection itself). Since SPM-calls from RWW-sections
20 * will fail to work. The routine will be called "bootloader__do_spm".
21 * Its principle assembler-code is depicted below (real code is a
22 * little machinedependend).
23 * Interfaces will be the 8-bit registers r10..r13, for details
24 * also see below. As also the pageaddress-registes (Z and rampZ)
25 * are interfaced via different registers, it is possible to call
26 * this routine via indirect call (icall).
27 * Traditionally it is also possible to rcall, therefore you can
28 * define "bootloader__do_spm" for your normal code via defsym at
29 * linking time.
30 * Example for an atmega8: "-Wl,--defsym=transfer_point=0x1826"
31 * (since BOOTLOADER_ADDRESS is 0x1800 and there are
32 * 2x19 = 38 = 0x26 byte for interrupts)
33 *
