6.4.7 Packet Bridge
Name bridgeTxPkt
Description
Variable is used in conjunction with bridgeTxDone. If bridgeTxPkt and bridgeTxDone are equal,
then it is permitted to write new packet data to bridgeTxPktBuffer. Setting bridgeTxPkt different than
bridgeTxDone will cause the contents of the packet buffer to be transmitted. Upon transmit
completion,
bridgeTxDone will be updated to match bridgeTxPkt.
Packet transmission can also be initiated by issuing a Packet Transmit command via HMI.

the next packet can be received.
