Hi,
I have some questions about flash programming

1. how many writes to flash can i made beetwen
FLASH->CR |= CR_PG_Set;
 and
FLASH->CR &= CR_PG_Reset;
is it possible to write here more data than 2 words ? (only 2 words are written in stm32 peripherial library).Are such writes limited ?

2. Is it possible to write to flash from procedure executed from flash ? or this procedure should be executet from RAM ?

3. when page is erased and flash is busy, the main program is running or executions is stopped until flash is ready ?

thanks in advance
