Data Buffer Management

Each MIL-1553 channel contains one pool of 3072 data index for all 32 RTs and each RT/subaddress/type pair’s message must be linked to one data buffer.

Using the data buffer assignment feature, each RT message can use a specific data index to share data buffer with other messages.

The mxfMIL1553RtSubsystemEnableSet() function allows assigning a data buffer index to a message on a RT/Type/Subaddress basis. The mxfMIL1553TxPeriodicUpdateMsgWrite() functions may be used to update a specific data buffer.
