如题。能否在一个32位地址开始连续写入若干个16位的数据。
void FlashHalfWord16Prog(uint32_t flash_addr, uint16_t data)
{
/* (1) Perform the data write (32-bit word) at the desired address */
/* (2) Wait until the BSY bit is reset in the FLASH_SR register */
/* (3) Check the EOP flag in the FLASH_SR register */
/* (4) clear it by software by writing it at 1 */
*(__IO uint32_t*)(flash_addr) = data; /* (1) */
while ((FLASH->SR & FLASH_SR_BSY) != 0) /* (2) */
{
/* For robust implementation, add here time-out management */
}
if ((FLASH->SR & FLASH_SR_EOP) != 0) /* (3) */
{
FLASH->SR |= FLASH_SR_EOP; /* (4) */
}
}
