D2D Interrupt Flag — This read-only flag reflects the status of the D2DINT Pin. The D2D interrupt flag can only be cleared by a
target specific interrupt acknowledge sequence.
0 External Interrupt is negated
1 External Interrupt is asserted
D2D Initiator Busy — This read-only status bit indicates that a D2D transaction is ongoing.
0 D2D initiator idle.
1 D2D initiator transaction ongoing.
Reserved, should be masked to ensure compatibility with future versions of this interface.
Transaction Read-Write Direction — This read-only bit reflects the direction of the transaction
0 Write Transaction
1 Read Transaction
Transaction Size — This read-only bit reflects the data size of the transaction
0 16-bit transaction.
1 8-bit transaction.
Reserved, should be masked to ensure compatibility with future versions of this interface.
Transaction Mode — This read-only bit reflects the mode of the transaction
0 Blocking transaction.
1 Non-blocking transaction.
Reserved, should be masked to ensure compatibility with future versions of this interface.
Transaction Address — Those read-only bits contain the address of the transaction
