INEPTXFSPCAVAIL |
IN Endpoint TxFIFO Space Avail (INEPTxFSpcAvail) Indicates the amount of free space available in the Endpoint TxFIFO. Values are in terms of 32-bit words. In DRD configurations (OTG_MODE = 0, 1, or 2) with dynamic FIFO sizing feature enabled (OTG_DFIFO_DYNAMIC = 1), the value of this field (before DIEPCTLi.TxFNum is programmed) is - the maximum value of (OTG_TX_HNPERIO_DFIFO_DEPTH, OTG_TX_DINEP_DFIFO_DEPTH_0) during reset, and - OTG_TX_DINEP_DFIFO_DEPTH_0, immediately after reset deassertion After DIEPCTLi.TxFNum is programmed, the value of this field will return OTG_TX_DINEP_DFIFO_DEPTH_i |
