#define FLASH_ACR_LATENCY_Pos (0U)
#define FLASH_ACR_LATENCY_Msk (0x1U << FLASH_ACR_LATENCY_Pos) /*!< 0x00000001 */
#define FLASH_ACR_LATENCY FLASH_ACR_LATENCY_Msk /*!< Latency */
其中的0U左移一位x2还是0啊?
#define FLASH_ACR_SLEEP_PD_Pos (3U)
#define FLASH_ACR_SLEEP_PD_Msk (0x1U << FLASH_ACR_SLEEP_PD_Pos) /*!< 0x00000008 */
3左移一位应该是6啊?请问是我理解错了吗? |
