It is used to set baud rate, parity check, number of data bits, stop bit. 它是用来设置波特率,奇偶校验,数据位数,停止位。
By synthesizing the parity check and CRC-4, a synthetic error-tolerant technology which can correct 1 code bit and checkout 2 code bits error, 4 code bits error, 2.7% of all 3 code bits error is presented. 通过综合运用奇偶校验和CRC-4校验,提出一种综合容错技术,能够纠错1位和检错2位、检错4位、检错2.7%的3位码元错。
