Host Management Interface (HMI)

7.4.1.5. Packet Received

Sets bridgeRxPkt = bridgeRxReady thus acknowledging receipt of the packet in

bridgeRxPktBuffer.

void PacketReceive( void )

{

int msgack = MSG_D;

MSG_C = MOP_PACKET_RECEIVE;

MSG_D = CVR_MULTIPLEX_OP;

while( !( ( msgack ^ MSG_D ) & ( 1 << MSG_TOGGLE_BO ) ) );

}

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 )

{

int msgack = MSG_D;

MSG_C = MOP_PACKET_TRANSMIT;

MSG_D = CVR_MULTIPLEX_OP;

while( !( ( msgack ^ MSG_D ) & ( 1 << MSG_TOGGLE_BO ) ) );

}

7.4.1.7. Goto Counters

Moves HMI data pointers to interrupt status variables (beginning at hackStatus).

void GotoCounters( void )

{

int msgack = MSG_D;

MSG_C = MOP_GOTO_COUNTERS;

MSG_D = CVR_MULTIPLEX_OP;

while( !( ( msgack ^ MSG_D ) & ( 1 << MSG_TOGGLE_BO ) ) );

}
