Hardware Abstraction Layer (HAL)
|
Interface to abstract away the driver-specific differences between TDM and I2S.
Application code should not rely on the specific contents of this struct. They are considered an implementation detail which is subject to change between platforms and/or HAL releases.

| void(* _cyhal_audioss_interface_t::invoke_user_callback) (struct _cyhal_audioss_s *obj, uint32_t hal_event) |
Invoke the user callback with the specified HAL event.
Only called after the user callback has been verified to not be null.
