<strong>RM0090</strong> USB on-the-go high-speed (OTG_HS) ● Reading the receive FIFO The application must ignore all packet statuses other than IN data packet (bx0010). Figure 385.

USB on-the-go high-speed (OTG_HS) <strong>RM0090</strong> SETUP transaction operates in the same way but has only one packet. The assumptions are: – The application is attempting to send two maximum-packet-size packets (transfer size = 1, 024 bytes). – The nonperiodic transmit FIFO can hold two packets (128 bytes for FS). – The nonperiodic request queue depth = 4. ● Normal bulk and control OUT/SETUP operations The sequence of operations for channel 1 is as follows: a) Initialize channel 1 b) Write the first packet for channel 1 c) Along with the last DWORD write, the core writes an entry to the nonperiodic request queue d) As soon as the nonperiodic queue becomes nonempty, the core attempts to send an OUT token in the current frame e) Write the second (last) packet for channel 1 f) The core generates the XFRC interrupt as soon as the last transaction is completed successfully g) In response to the XFRC interrupt, de-allocate the channel for other transfers h) Handling nonACK responses 1263/1416 Doc ID 018909 Rev 3
