The application is expected to write the requests as and when the request queue space is
available and until the XFRC interrupt is received.
• Bulk and control IN transactions
A typical bulk or control IN pipelined transaction-level operation is shown in Figure 346.
See channel 2 (ch_2). The assumptions are:
– The application is attempting to receive two maximum-packet-size packets
(transfer size = 1 024 bytes).
– The receive FIFO can contain at least one maximum-packet-size packet and two
status words per packet (72 bytes for FS).
– The non-periodic request queue depth = 4.
