This write one to clear register indicates that the DCLKCNT has counted down to zero. The DCLKCNT is used by software to drive spurious DCLKs to the FPGA. Software will poll this bit after writing DCLKCNT to know when all of the DCLKs have been sent.

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.
