1) This scan engine is transmitting the data.
2) The host system sets RTS signal to L-level for the command data packet transmission.
3) This scan engine, after confirming that CTS signal has been set to L-level, suspends
data transmission and sets RTS signal to L-level.
4) The host system, after confirming that CTS signal has been set to L-level, transmits
command data packets.
5) The host system sets back RTS signal to H-level.
6) This scan engine, after confirming that CTS signal has been set to H-level, sets back
RTS signal to H-level.
7) This scan engine responses to the command data packet.
8) This scan engine retransmits the data suspened in 1)
9) The host system sets RTS signal to L-level to send response to the data being sent.
10) This scan engine detects that CTS signal has been set to L-level and sets RTS signal to
L-level.
11) The host system send out the response.
12) The host system sets back RTS signal to H-level.
13) This scan engine detects that CTS signal has been set back to H-level and sets back
RTS signal to H-level.
Note: When ACK/NAK protocol is not selected, the sequence described in 7) and from 9) to
13) shall not occur.
