VRQ hardware Flush enable 0 RW 0x0 This value will be loaded into a count-down
counter triggered by a falling-edge of any bit of
VRQ Enable register (0x560). The count-down is
based on internal CORE_CLK. The purpose of
this counter is to allow hardware to drain out
certain pending DMA requests within WDMA
pipeline and PCIE core. Once the timer expires,
hardware shall invoke the Automatic VRQ Flush
Procedure. A value 0x0 in this register effectively
zeroes this timer count.
