OTG_HS device IN endpoint transmit FIFO status register
(OTG_HS_DTXFSTSx) (x = 0..5, where x = Endpoint_number)
Address offset for IN endpoints: 0x918 + 0x20 + x
This read-only register contains the free space information for the Device IN endpoint
TxFIFO.
OTG_HS device endpoint-x transfer size register (OTG_HS_DOEPTSIZx)
(x = 1..5, where x = Endpoint_number)
Address offset: 0xB10 + 0x20 * x
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_HS_DOEPCTLx), the core modifies this register. The application can only read this
register once the core has cleared the Endpoint enable bit.
