基于TI给出的sys/bios代码，在AM3359上运行并配置了UART参数，但是通过串口和PC通讯时能接收0x00~0xFE的数据却怎么也无法收到0xFF。参数配置如下

const UART_Params UART_HBUS = {
UART_MODE_BLOCKING, /* readMode */
UART_MODE_BLOCKING, /* writeMode */
(~((uint32_t)0U)), /* readTimeout */
(~((uint32_t)0U)), /* writeTimeout */
NULL, /* readCallback */
NULL, /* writeCallback */
UART_RETURN_FULL, /* readReturnMode */
UART_DATA_BINARY, /* readDataMode */
UART_DATA_BINARY, /* writeDataMode */
UART_ECHO_OFF, /* readEcho */
115200, /* baudRate */
UART_LEN_8, /* dataLength */
UART_STOP_ONE, /* stopBits */
UART_PAR_NONE, /* parityType */
NULL, /* readCallback2 */
NULL, /* writeCallback2 */
};
