6 - 16 Symbol PL4507 Decoder Integration Guide
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 decoder sends data packets continuously, with no ACK/NAK handshaking to
pace the transmission. The host, if overrun, can use hardware handshaking to temporarily delay decoder
transmissions. At the end of transmission, the decoder 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.
