void noc_inline_dw_write(uint64_t addr, uint32_t val, uint8_t be = 0xF, uint8_t noc = noc_index, uint8_t vc = NOC_UNICAST_WRITE_VC)

Initiates an asynchronous write of a 32-bit value to a NOC destination. Typically used for writing registers, but can be used for memory locations as well. The destination is specified as a 64-bit NOC address (see noc_async_write). The advantage over using noc_async_write is that we don’t use a Tensix L1 memory source location; the write value is written directly into a register. Unlike using noc_async_write, there are also no address alignment concerns. Also, see noc_async_write_barrier.

The destination node can be either a Tensix core+L1 memory address or a PCIe controller; This API does not support DRAM addresses.
