Field : Level - level | |
Stalls the transaction in the write data FIFO until the number of occupied slots in the write data FIFO exceeds the level. Note that the transaction is released before this level is achieved if the network receives the WLAST beat or the write FIFO becomes full. Field Access Macros: | |

WARNING: The C register and register group struct declarations are provided for convenience and illustrative purposes. They should, however, be used with caution as the C language standard provides no guarantees about the alignment or atomicity of device memory accesses. The recommended practice for writing hardware drivers is to use the SoCAL access macros and alt_read_word() and alt_write_word() functions.
