  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  *
