TI中文支持网你好，ti的员工，有以下两个问题：
1、cc2541串口传输看资料时可以传送9位数据，第9位是可选的数据位或者奇偶校验位，请问一下，当第九位用作数据位时，是不是失能掉U0UCR中的PARITY位，就可以把D9中的数据当作第九位传送出去？如果是这样，请问接收到的第9位数据存放在哪里？
2、蓝牙串口可以直接和max485对接通讯吗？
cedar_xuesong：
If the BIT9 and PARITY bits in register UxUCR are set high, parity generation and detection is enabled. The parity is computed and transmitted as the ninth bit, and during reception, the parity is computed and compared to the received ninth bit. If there is a parity error, the UxCSR.ERR bit is set high. This bit is cleared when UxCSR is read.
看手册的意思是：将奇偶校验位作为第9位来处理了
