TI中文支持网请问，两块AM335X芯片通过SPI相连接，是D0<–>D0, D1<–>D1这样连接吗？
Nancy Wang：
可以按照上图的示意连接。
SPIDAT [1:0] 可以独立配置成输入或者输出，具体要看是做主还是从。
McSPI has a unified SPI port control: SPIDAT [1:0] can be independently configured as receive or transmit lines. The user has the responsibility to program which data line to use and in which direction (receive or transmit), according to the external slave/master connection.
