Вот даташит, к примеру,
на семество "A". Здесь есть все. Внимательно читать разделы
29. Program and Debug Interface
30. Memory Programming
Прочитал) Например есть следующая команда и о ней написанно:
30.12.3.4 Load Page Buffer
The Load Flash Page Buffer and Load EEPROM Page Buffer commands are used to load one
byte of data into the Flash and EEPROM page buffers.
1. Load the NVM CMD register with the Load Flash/EEPROM Page Buffer command.
2. Write the selected memory address by doing a PDI Write operation.
Since the Flash page buffer is word accessing and the PDI uses byte addressing, the PDI must
write the Flash Page Buffer in correct order. For the write operation, the low-byte of the word
location must be written before the high-byte. The low-byte is then written into the temporary
register. The PDI then writes the high-byte of the word location, and the low-byte is then written
into the word location page buffer in the same clock cycle.
The PDI interface is automatically halted, before the next PDI instruction can be executed.
Вроде всё понятно... но куда писать байт который хочу положить в буффер???
