dclkstat
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.

Important: To prevent indeterminate
system behavior, reserved areas of memory must not be accessed by software or
hardware. Any area of the memory map that is not explicitly defined as a register
space or accessible memory is considered reserved.
