一条SPI总线上有多个L6470，不使用菊花链

是否可以在同一SPI总线上使用多个L6470电机驱动器IC - 常见的SDI，SDO，CK线路，但每个L6470都有独立的芯片选择信号？

当连接多个芯片时，我的实验板没有显示SDO上的任何数据。
我认为只要该芯片上的芯片选择不活动，SDO端口就是高阻抗？

Is it possible to use multiple L6470 motor driver ICs on the same SPI bus - common SDI, SDO, CK line, but separate chipselect signals for each L6470?

My experimental board doesn't show any data on SDO when more than one chip is connected.
I thought that SDO ports are high impedance as long as chipselect at that chip is not active?
