L9305 Daisy Chain SPI

[YJL]

Does anyone know if the L9305 supports Daisy chain communication?

有人知道L9305是否支持菊花链通讯？

I am debugging an ECU containing two SPI Daisy chain communication L9305. Currently, after testing, the 9305 that is separately controlled and connected to MCU MOSI pin is normal, but the instruction sent to the 9305 that is connected to MCU MISO chip cannot be input correctly. Its SDI pin is like the data output after the instruction of the presequence is executed, rather than the remote control instruction issued by the MCU. I'm wondering if the 9305 supports SPI Daisy chain communication.

我在调试一块含有两片SPI菊花链通讯L9305的ECU，目前测试下来，单独控制和MCU MOSI pin脚连接的9305是正常的，但给 连接MCU MISO片的9305发送指令无法正确输入，它的SDI pin像是前序片的指令执行后的数据输出，而不是MCU发出的远端控制指令。我很疑惑到底9305能否支持SPI菊花链通讯。
