:SOC_TWAI_SUPPORTED: - **TWAI**: between calls to :cpp:func:`twai_driver_install` and :cpp:func:`twai_driver_uninstall` (only when the clock source is set to :cpp:enumerator:`TWAI_CLK_SRC_APB`).
:SOC_BT_SUPPORTED and esp32: - **Bluetooth**: between calls to :cpp:func:`esp_bt_controller_enable` and :cpp:func:`esp_bt_controller_disable`. If Bluetooth Modem-sleep is enabled, the ``ESP_PM_APB_FREQ_MAX`` lock will be released for the periods of time when radio is disabled. However the ``ESP_PM_NO_LIGHT_SLEEP`` lock will still be held, unless :ref:`CONFIG_BTDM_CTRL_LOW_POWER_CLOCK` option is set to "External 32kHz crystal".

The following peripheral drivers are not aware of DFS yet. Applications need to acquire/release locks themselves, when necessary:
.. list::
- PCNT
- Sigma-delta
:SOC_PCNT_SUPPORTED: - The legacy PCNT driver
:SOC_SDM_SUPPORTED: - The legacy Sigma-delta driver
- The legacy timer group driver
:SOC_MCPWM_SUPPORTED: - MCPWM
:SOC_MCPWM_SUPPORTED: - The legacy MCPWM driver
