Macro Definition Documentation

◆ dg_configEFLASH_MASS_ERASE_TIME

#define dg_configEFLASH_MASS_ERASE_TIME 160000

EFLASH memory mass erase time in usec.

EFLASH memory mass erase time. Minimum: 80000 usec Maximum: 160000 usec

APP EXPERT-only

◆ dg_configEFLASH_PAGE_ERASE_TIME

#define dg_configEFLASH_PAGE_ERASE_TIME 160000

EFLASH memory page erase time in usec.

EFLASH memory page erase time. Minimum: 80000 usec Maximum: 160000 usec

APP EXPERT-only

◆ dg_configEFLASH_WORD_WRITE_TIME

#define dg_configEFLASH_WORD_WRITE_TIME 16

EFLASH memory one word write time in usec.

EFLASH memory one word write time. Minimum: 8 usec Maximum: 16 usec

APP EXPERT-only

◆ dg_configFLASH_POWER_DOWN

#define dg_configFLASH_POWER_DOWN (0)

When set to 1, the QSPI FLASH is put to power-down state during sleep.

APP

◆ dg_configHW_FCU_WAIT_CYCLES_MODE

#define dg_configHW_FCU_WAIT_CYCLES_MODE (2)

Activate EFLASH optimum wait cycle functionality.

EFLASH wait cycles depend on AHB bus frequency and VDD voltage level. Enabling this functionality EFLASH is configured with the correct wait cycles.

When set to 0, the EFLASH wait cycles are configured to the default and secure option of 2 wait cycles, regardless of the AHB frequency and VDD voltage level. When set to 1, the EFLASH wait cycles are dynamically configured based on AHB bus frequency and VDD voltage level. When set to 2, in addition to dynamic configuration of wait cycles in EFLASH, like when is set to 1, the AHB frequency and VDD voltage level are monitored in order to indicate if there was a change in the above parameters without triggering wait cycles change. In this mode, extra code will be added in order to monitor the above settings and in case of an untraced change an ASSERT_WARNING will be triggered.

Note: It is not recommended to set dg_configHW_FCU_WAIT_CYCLES_MODE to 2 in production code because it will add extra code and will trigger an ASSERT_WARNING when (dg_configIMAGE_SETUP == DEVELOPMENT_MODE) when an untraced change is detected. It is recommended to use this setting during development phase.

◆ dg_configIMAGE_FLASH_OFFSET

#define dg_configIMAGE_FLASH_OFFSET (0)

Offset of the image if not placed at the beginning of QSPI Flash.

APP EXPERT-only

◆ dg_configPOWER_1V8_ACTIVE

#define dg_configPOWER_1V8_ACTIVE (2)

The rail from which the external Flash is powered, if an external Flash is used.

FLASH_IS_NOT_CONNECTED
FLASH_CONNECTED_TO_1V8

APP

When set to 1, the 1V8 rail is powered, when the system is in active state. When set to 2 the rail configuration will be defined by the application

APP

◆ dg_configPOWER_1V8_SLEEP

#define dg_configPOWER_1V8_SLEEP (2)

When set to 1, the 1V8 is powered during sleep. When set to 2 the rail configuration will be defined by the application.

APP

◆ dg_configQSPI_AUTOMODE_ENABLE

#define dg_configQSPI_AUTOMODE_ENABLE (1)

Enable qspi_automode.

Enable qspi_automode to access QSPI flash. May be disabled when QSPI flash is not accessible.

1 : Enabled
0 : Disabled

APP EXPERT-only

◆ dg_configQSPI_DRIVE_CURRENT

#define dg_configQSPI_DRIVE_CURRENT (HW_QSPI_DRIVE_CURRENT_4)

Set the Drive Strength of the QSPI Controller.

APP EXPERT-only

See also: HW_QSPI_DRIVE_CURRENT

◆ dg_configQSPI_FLASH_AUTODETECT

#define dg_configQSPI_FLASH_AUTODETECT (0)

Enable the Flash Auto-detection mode for QSPIC.

Warning: THIS WILL GREATLY INCREASE THE CODE SIZE AND RETRAM USAGE!!! MAKE SURE YOUR PROJECT CAN SUPPORT THIS.

APP EXPERT-only

◆ dg_configQSPI_FLASH_AUTODETECT_RESET_DELAY

#define dg_configQSPI_FLASH_AUTODETECT_RESET_DELAY (12000)

Minimum required delay after flash reset sequence in usec.

When the dg_configFLASH_AUTODETECT is enabled, a flash reset sequence must be applied before reading the JEDEC ID. Since the memory is unknown, the corresponding reset delay cannot be fetched by the flash memory driver.

Warning: This delay must be equal or higher than the minimum required reset time of all supported flash memories. Consider re-defining this macro, if a memory with higher reset delay needs to be supported.

APP EXPERT-only

◆ dg_configQSPI_FLASH_CONFIG

#define dg_configQSPI_FLASH_CONFIG qspi_mx25u3235_cfg

The Flash Driver configuration structure.

The configuration structure must be in the include path of the compiler

APP

◆ dg_configQSPI_FLASH_CONFIG_VERIFY

#define dg_configQSPI_FLASH_CONFIG_VERIFY (0)

Flash device configuration verification.

When set to 1, the Flash device id configuration is checked against the JEDEC ID read from the controller.

Applicable only when flash auto detection is not enabled.

APP

◆ dg_configQSPI_FLASH_HEADER_FILE

#define dg_configQSPI_FLASH_HEADER_FILE "qspi_mx25u3235_v2.h"

The Flash Driver header file to include.

The header file must be in the include path of the compiler

APP

◆ dg_configQSPI_FLASH_MAX_WRITE_SIZE

#define dg_configQSPI_FLASH_MAX_WRITE_SIZE (128)

Set the flash page size.

APP EXPERT-only

◆ dg_configQSPI_FLASH_POWER_DOWN

#define dg_configQSPI_FLASH_POWER_DOWN (1)

When set to 1, the system activates the QSPI flash power-down mode when it enters sleep in order to minimize overall power consumption.

APP

◆ dg_configQSPI_MEMORY_CONFIG_TABLE_HEADER

#define dg_configQSPI_MEMORY_CONFIG_TABLE_HEADER "qspi_memory_config_table_internal.h"

The header file where the QSPI flash configuration table is instantiated.

This compilation option has effect only when the QSPI flash auto detection is enabled.

APP EXPERT-only

◆ dg_configQSPI_SLEW_RATE

#define dg_configQSPI_SLEW_RATE (HW_QSPI_SLEW_RATE_0)

Set the Slew Rate of the QSPI Controller.

APP EXPERT-only

See also: HW_QSPI_SLEW_RATE

◆ dgconfigQSPI_ERASE_IN_AUTOMODE

#define dgconfigQSPI_ERASE_IN_AUTOMODE (1)

Select whether the QSPI Flash memory will be erased in Auto or in Manual Access Mode.
