7.4.1.5. Packet Received
Sets bridgeRxPkt = bridgeRxReady thus acknowledging receipt of the packet in
bridgeRxPktBuffer.
void PacketReceive( void )
{
}
7.4.1.6. Packet Transmit
Sets bridgeTxPkt = bridgeTxPktDone+1 thus initiating transmission of the contents of
bridgeTxPktBuffer. Presumably bridgeTxPktBuffer has been previously written with valid
packet data.
void PacketTransmit( void )
{
}
7.4.1.7. Goto Counters
Moves HMI data pointers to interrupt status variables (beginning at hackStatus).
void GotoCounters( void )
{
}
