Multipacket Option
Parameter # F0h, 4Eh
This parameter controls ACK/NAK handshaking for multi-packet transmissions.
• Multi-Packet Option 1
: The host sends an ACK / NAK for each data packet during a multi-packet
transmission.
• Multi-Packet Option 2
: The imager sends data packets continuously, with no ACK/NAK handshaking to
pace the transmission. The host, if overrun, can use hardware handshaking to temporarily delay imager
transmissions. At the end of transmission, the imager waits for a CMD_ACK or CMD_NAK.
• Multi-Packet Option 3
: Option 3 is the same as option 2 with the addition of a programmable interpacket
delay.
