                                  USB DEVICE STATES DATA TYPE

Note

• (1) 'Universal Serial Bus Specification Rev 2.0', section 9.1.1 defines seven visible device states:

  • (a) SL_USBD_DEVICE_STATE_INIT : Device is not attached to the USB.

  • (b) SL_USBD_DEVICE_STATE_ATTACHED : Device is attached to the USB, but not powered.

  • (c) USBD_DEV_STATE_POWERED : Device is attached to the USB and powered, but has not been reset.

  • (d) SL_USBD_DEVICE_STATE_DEFAULT : Device is attached to the USB and powered and has been reset, but has not been assigned a unique address. Device responds at the default address.

  • (e) SL_USBD_DEVICE_STATE_ADDRESSED : Device is attached to the USB, powered, has been reset, and a unique device address has been assigned. Device is not configured.

  • (f) SL_USBD_DEVICE_STATE_CONFIGURED : Device is attached to the USB, powered, has been reset, has a unique address, is configured, and is not suspended. The host may now use the function provided by the device.

  • (g) SL_USBD_DEVICE_STATE_SUSPENDED : Device is, at minimum, attached to the USB and is powered and has not seen bus activity for 3 ms. It may also have a unique address and be configured for use. However, because the device is suspended, the host may not use the device's function.

• (2) An additional state is added (USBD_DEV_STATE_START) to determine if the device controller has been initialized.

sl_usbd_core_init#

sl_status_t sl_usbd_core_init (void )

FUNCTION PROTOTYPES.

CONFIGURATION OVERRIDE FUNCTIONS USBD CORE FUNCTIONS

Note(s) : (1) USB Spec 2.0, Section 5.5 states "Control transfers allow access to different parts of a device. Control transfers are intended to support configuration/command/status type communication flows between client software and its function".

                                              FRAME

Note(s) : (1) Section 8.3.3 of USB spec 2.0 describes the frame number as: "The frame number field is an 11-bit field that is incremented by the host on a per-frame basis. The frame number field rolls over upon reaching its maximum value of 7FFH and is sent only in SOF tokens at the start of each (micro)frame."
