rx_valid

The debugger sets the rx_valid bit to indicate the data scanned into DBG_SR[34:3] is valid data to
be written to RX. When this bit is set, the data scanned into the DBG_SR will be written to RX
following an Update_DR. If rx_valid is not set Update_DR does not affect RX.
This bit does not affect the actions of the flush_rr or hs_download bits.
