HAL MDF constants migration

This section provides information about the HAL MDF constants migration.

Note

  • In HAL1, a single driver handles both MDF and ADF peripherals.

  • In HAL2, the HAL MDF driver has been split into two separate drivers HAL MDF and HAL ADF. For more details, see : MDF specific concept.

  • In HAL1, there are some constants applicable for:

    • Both MDF and ADF peripheral.

    • MDF peripheral only.

    • ADF peripheral only.

  • In the following migration document when the constant is applicable for both MDF and ADF the migration describes how to move from HAL1 MDF to HAL2 MDF. The same applies for ADF, example:

  • In HAL1, MDF_CLOCK_TRIG_RISING_EDGE constant becomes :

    • HAL_MDF_OUT_CLOCK_TRIG_RISING_EDGE in HAL2 MDF driver.

    • HAL_ADF_OUT_CLOCK_TRIG_RISING_EDGE in HAL2 ADF driver.

  • When the constant is applicable only for MDF the migration provides the equivalent for MDF.

  • When the constant is applicable only for ADF the migration provides the equivalent for ADF.
