The algorithm represented on
pipe.
Figure 22-24. Pipe Activation Algorithm
As long as the pipe is not correctly configured (UPSTAn.CFGOK is zero), the controller can not
send packets to the device through this pipe.
The UPSTAn.CFGOK bit is set only if the configured size and number of banks are correct com-
pared to their maximal allowed values for the pipe (see
maximal FIFO size (i.e. the DPRAM size).
See
Once the pipe is correctly configured (UPSTAn.CFGOK is zero), only the PTOKEN and INTFRQ
fields can be written by software. INTFRQ is meaningless for non-interrupt pipes.
When starting an enumeration, the user 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 user 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 an 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 user writes the new address into the USB Host
Address for Pipe n field in the USB Host Device Address register (UHADDR.UHADDRPn). All
following requests, on all pipes, will be performed using this new address.
When the host controller sends an USB reset, the UHADDRPn field is reset by hardware and the
following host requests will be performed using the default device address 0.
