• In the Idle state, the pad is put in low power consumption mode, i.e., the differential receiver
• In the Active state, the pad is working.
memory allocation and de-allocation may affect only higher pipes/endpoints.
modifies temporarily the controller DPRAM pointer and size for this pipe/endpoint, but
nothing changes in the DPRAM, so higher endpoints seem to not have been moved and their
data is preserved as far as nothing has been written or received into them while changing the
allocation state of the first pipe/endpoint.
n 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.
of the USB pad is off, and internal pull-down with strong value(15K) are set in both DP/DM to
avoid floating lines.
