Bitslip
Use bitslip circuitry to insert latencies in increments of one fast clock cycle for data word alignment.
The data slips one bit for every pulse of the rx_bitslip_ctrl signal. Because it takes at least two core clock cycles to clear the undefined data, wait at least four core clock cycles before checking if the data is aligned.
After enough bitslip signals are sent to rollover the bitslip counter, the rx_bitslip_max status signal is asserted after four core clock cycles to indicate that the bitslip counter rollover point has reached its maximum counter value.
