NOTE: *These status bits are appended to the corresponding data character in the receive FIFO. A read of the status provides these bits
(7:5) from the top of the FIFO together with bits (4:0). These bits are cleared by a “reset error status” command. In character mode they are
discarded when the corresponding data character is read from the FIFO. In block error mode, block error conditions must be cleared by using
the error reset command (command 4x) or a receiver reset.
