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.

This bit is write one to clear. This bit gets set after the DCLKCNT has counted down to zero (transition from 1 to 0).

Value Description
0x0 DCLKCNT is still counting down.
0x1 DCLKCNT is done counting down.
RW 0x0
