  Device Address n Configuration Registers (DEVADDn) (n = 0 to A) 
DEVADDn is a register that specifies the address and port number of the hub to which the 
communication target peripheral device is connected and that also specifies the transfer speed of 
the peripheral device for PIPE0 to PIPEA. 
When the host controller function is selected, this register should be set before starting 
communication using each pipe. 
The bits in this register should be modified while no valid pipes are using the settings of this 
register. Valid pipes refer to the ones satisfying both of condition 1 and 2 below. 
1.  This register is selected by the DEVSEL bits as the communication target. 
2.  The PID bits are set to BUF for the selected pipe or the selected pipe is the DCP with SUREQ 
being 1. 
 
This register is initialized by a power-on reset.
