- Channel configuration was done by channel allocation, in :cpp:func:`sdm_new_channel`. In the new driver, only the ``density`` can be changed at runtime, by :cpp:func:`sdm_channel_set_pulse_density`. Other parameters like ``gpio number`` and ``prescale`` are only allowed to set during channel allocation.
- Before further channel operations, users should **enable** the channel in advance, by calling :cpp:func:`sdm_channel_enable`. This function helps to manage some system level services, like **Power Management**.

Legacy Timer Group Driver is Deprecated
---------------------------------------
Timer Group driver has been redesigned into :doc:`GPTimer <../../../api-reference/peripherals/gptimer>`, which aims to unify and simplify the usage of general purpose timer.
Although it is recommended to use the new driver APIs, the legacy driver is still available in the previous include path ``driver/timer.h``. However, by default, including ``driver/timer.h`` triggers the build warning below. The warning can be suppressed by the Kconfig option :ref:`CONFIG_GPTIMER_SUPPRESS_DEPRECATE_WARN`.

Legacy Timer Group Driver is Removed
------------------------------------
The legacy timer group driver ``driver/timer.h`` is deprecated since version 5.0 (see :ref:`deprecate_gptimer_legacy_driver`). Starting from version 6.0, the legacy driver is completely removed. The new driver is placed in the :component:`esp_driver_gptimer`, and the header file path is ``driver/gptimer.h``.

- 更新前，通道配置由通道分配在 :cpp:func:`sdm_new_channel` 完成。在新驱动中，只有 ``density`` 可在运行时由 :cpp:func:`sdm_channel_set_pulse_density` 更新。其他参数如 ``gpio number``、 ``prescale`` 只能在通道分配时进行设置。
- 在进行下一步通道操作前，用户应通过调用 :cpp:func:`sdm_channel_enable` 提前 **使能** 该通道。该函数有助于管理一些系统级服务，如 **电源管理**。

hint: "When operating in full-duplex mode at high frequencies, the device may not read data correctly.\nTry using IOMUX pins to increase the frequency limit or switch to half-duplex mode.\nNote that the SPI master can only operate at divisors of 80 MHz, and the driver always selects the closest available frequency to your configuration.\nSpecify SPI_DEVICE_NO_DUMMY to bypass this check. This allows higher output speeds but may result in unreliable data reads."
