With a 16- or 20-bit width data, the word aligner starts looking for the programmed
8-bit, 16-bit, or 32-bit word alignment pattern in the received data stream as soon as
rx_digitalreset is de-asserted low. It aligns to the first word alignment pattern
received regardless of the logic level driven on the rx_enapatternalign signal. Any
word alignment pattern received thereafter in a different word boundary does not
cause the word aligner to re-align to this new word boundary. After the initial word
alignment, following de-assertion of the rx_digitalreset signal, if a word
re-alignment is required, you must use the rx_enapatternalign signal.
