8.2.7 boot_page_fill Macro

Place a word in the bootloader temporary page buffer corresponding to the flash address.

Include

<avr/boot.h>

Prototype

void boot_page_fill(unsigned int address, unsign int value);

Remarks

This macro places the value specified in the bootloader temporary page buffer corresponding to the flash address. The address is a byte address; however, AVR devices writes words to the buffer, so for each 16-bit word to be written, increment the address by 2. The LSB of the data is written to the lower address; the MSB of the data is written to the higher address.

Example

#include <avr/boot.h>
int main(void)
{
  boot_page_fill(0x100, 0x55);
}
