The following shows an example of a (3n –1)-byte data transfer that requires the use of a pad. The Aurora 8B/10B core appends a pad character for a frame with an odd number of bytes as per the protocol requirement. A transfer of 3n –1 data bytes requires two fulln -byte data words and one partial data word. In this example, s_axi_tx_tkeep is set to N–1 to indicate n –1 valid bytes in the last data word.
