noc_async_write_multicast_loopback_src

inline void noc_async_write_multicast_loopback_src(std::uint32_t src_local_l1_addr, std::uint64_t dst_noc_addr_multicast, std::uint32_t size, std::uint32_t num_dests, bool linked = false, uint8_t noc = noc_index)

Initiates an asynchronous write from a source address in L1 memory on the Tensix core executing this function call to a rectangular destination grid. This API is the same as noc_async_write_multicast but with the multicast sender being part of the multicast destinations. Refer to noc_async_write_multicast for more details.

Return value: None
