OTG_FS device IN endpoint transmit FIFO status register
(OTG_FS_DTXFSTSx) (x = 0..3, where x = Endpoint_number)
Address offset for IN endpoints: 0x918 + (Endpoint_number × 0x20) This read-only register
contains the free space information for the Device IN endpoint TxFIFO.
OTG_FS device endpoint-x transfer size register (OTG_FS_DOEPTSIZx)
(x = 1..3, where x = Endpoint_number)
Address offset: 0xB10 + (Endpoint_number × 0x20)
Reset value: 0x0000 0000
The application must modify this register before enabling the endpoint. Once the endpoint is
enabled using Endpoint Enable bit of the Device endpoint-x control registers (EPENA bit in
OTG_FS_DOEPCTLx), the core modifies this register. The application can only read this
register once the core has cleared the Endpoint enable bit.
Bit 31 Reserved
15:0 INEPTFSAV: IN endpoint TxFIFO space avail ()
Indicates the amount of free space available in the Endpoint TxFIFO.
Values are in terms of 32-bit words:
Applies to isochronous OUT endpoints only.
This is the data PID received in the last packet for this endpoint.
0x0: Endpoint TxFIFO is full
0x1: 1 word available
0x2: 2 words available
0xn: n words available (where 0 < n < 512)
0x200: 512 words available
