Other Parts Discussed in Thread: TDA4VM
Hello TI
咨询TDA4VM SPI相关问题
1.TDA4VM 中MCSPI 中的 D0 D1是否可以任意配置成SPI的 DIN或者DOUT, 即MISO或者MOSI。
2.和外设SPI通讯时,片选信号SPI CS是否可任意选为 CS0 CS1 CS2 CS3, 并不一定非得选CS0.
谢谢!

另外请问一下main domai下,SPI能否做 slave
没有看到限制,应该是可以的,详细请阅读 12.1.5.2.6 MCSPI in Slave Mode
不是,硬件上可以接,软件上再通过SPIENSLV 配到channel 0,手册上有说明。
Only channel 0 can be configured as slave, but the chip-enable signal can be connected to any SPIEN[i] pin and then rerouted internally to channel 0 (the [22-21] SPIENSLV bit field).
