In renewed frame, Packet A’s FIFO interchanges with packet B’s FIFO, and the
transaction uses the same flow.
If SOF token is not received by error and so on, this data is lost because the frame is
not renewed. There is no problem in receiving PID and if frame data is received with
CRC error, USB sets LOST to STATUS on FRAME register, and exact frame number
is unknown. However, in this case, SOF is asserted and FIFO condition is renewed. If
SOF token is received without transmit and transfer Isochronous in frame, UDC
clears FIFO (X Condition) and sets STATUS to FULL.
These are shown in Figure 3.16.12.
Note : EPx_DATASET changes at 2 clocks of 12MHz after receiving SOF. Read data from FIFO after
EPx_DATASET is rising.
