Address Setup
Remote Wake-Up
As long as the pipe is not correctly configured (CFGOK = 0), the controller can not send packets
to the device through this pipe.
The CFGOK bit is set by hardware only if the configured size and number of banks are correct
compared to their maximal allowed values for the pipe (see
maximal FIFO size (i.e. the DPRAM size).
See
Once the pipe is correctly configured (CFGOK = 1), only the PTOKEN and INTFRQ bit-fields can
be modified by software. INTFRQ is meaningless for non-interrupt pipes.
When starting an enumeration, the firmware gets the device descriptor by sending a
GET_DESCRIPTOR USB request. This descriptor contains the maximal packet size of the
device default control endpoint (bMaxPacketSize0) and the firmware re-configures the size of
the default control pipe with this size parameter.
Once the device has answered the first host requests with the default device address 0, the host
assigns a new address to the device. The host controller has to send a USB reset to the device
and to send a SET_ADDRESS(addr) SETUP request with the new address to be used by the
device. Once this SETUP transaction is over, the firmware writes the new address into the
HADDR bit-field. All following requests, on all pipes, will be performed using this new address.
When the host controller sends a USB reset, the HADDR bit-field is reset by hardware and the
following host requests will be performed using the default device address 0.
The controller host mode enters the Suspend state when the SOFE bit is cleared. No more
“Start of Frame” is sent on the USB bus and the USB device enters the Suspend state 3 ms
later.
The device awakes the host by sending an Upstream Resume (Remote Wake-Up feature).
When the host controller detects a non-idle state on the USB bus, it raises the Host Wake-Up
