Detailed Description

Macro Definition Documentation

#define __HAL_FLASH_ART_DISABLE

(

)

CLEAR_BIT(FLASH->ACR, FLASH_ACR_ARTEN)

Disable the FLASH Adaptive Real-Time memory accelerator.

Return values

none

Definition at line 239 of file stm32f7xx_hal_flash.h.

#define __HAL_FLASH_ART_ENABLE

(

)

SET_BIT(FLASH->ACR, FLASH_ACR_ARTEN)

Enable the FLASH Adaptive Real-Time memory accelerator.

Note

The ART accelerator is available only for flash access on ITCM interface.

Return values

none

Definition at line 233 of file stm32f7xx_hal_flash.h.

#define __HAL_FLASH_ART_RESET

(

)

(FLASH->ACR |= FLASH_ACR_ARTRST)

Resets the FLASH Adaptive Real-Time memory accelerator.

Note

This function must be used only when the Adaptive Real-Time memory accelerator is disabled.

Return values

None

Definition at line 247 of file stm32f7xx_hal_flash.h.

#define __HAL_FLASH_CALC_BOOT_BASE_ADR

(

__ADDRESS__

)

((__ADDRESS__) >> 14)

Calculate the FLASH Boot Base Adress (BOOT_ADD0 or BOOT_ADD1)

Note

Returned value BOOT_ADDx[15:0] corresponds to boot address [29:14].

Parameters

<strong>ADDRESS</strong>

FLASH Boot Address (in the range 0x0000 0000 to 0x2004 FFFF with a granularity of 16KB)

Return values

The	FLASH Boot Base Adress
