+    Initiates an asynchronous write from a source address in L1 memory on the
+    Tensix core executing this function call to a rectangular destination grid.
+    The destinations are specified using a uint64_t encoding referencing an
+    on-chip grid of nodes located at NOC coordinate range
+    (x_start,y_start,x_end,y_end) and a local address created using
+    *get_noc_multicast_addr* function. Also, *see noc_async_write_barrier*.
+
+    The destination nodes can only be a set of Tensix cores + L1 memory address.
+    The destination nodes must form a rectangular grid. The destination L1
+    memory address must be the same on all destination nodes.
+
+    With this API, the multicast sender cannot be part of the multicast
+    destinations. If the multicast sender has to be in the multicast
+    destinations (i.e. must perform a local L1 write), the other API variant
+    *noc_async_write_multicast_loopback_src* can be used.
+
+    Note: The number of destinations needs to be non-zero. Besides that,
+    there is no restriction on the number of destinations, i.e. the
+    multicast destinations can span the full chip. However, as mentioned
+    previously, the multicast source cannot be part of the destinations. So, the
+    maximum number of destinations is 119.
