8. USB Bus Timing

8.1 Bulk IN Transaction

Figure 8-1 shows the data timing of a Bulk IN transaction from USB host. When the LSI

receives IN packet from the host PC, it asserts RXACT and drives 3 bytes received

data on SIE bus. External SIE logic receives the data, checks the information of

address, endpoint and CRC if necessary. If it finds the data valid, the SIE returns the

DATA packet to be transmitted. Finally the LSI receives ACK packet and finishes a Bulk

IN transaction.
