Figure 22-9. Pad Behavior
• In the Idle state, the pad is put in low power consumption mode, i.e., the differential receiver of
• In the Active state, the pad is working.

as far as nothing has been written or received into them while changing the allocation state of
the first pipe/endpoint.
Status register (UESTAn.CFGOK) is set only if the configured size and number of banks are
correct compared to their maximal allowed values for the endpoint and to the maximal FIFO
size (i.e. the DPRAM size), so the value of CFGOK does not consider memory allocation
conflicts.
the USB pad is off, and internal pull-down with strong value(15K) are set in both DP/DM to
avoid floating lines.
