DLPC6540: DLPC6540+DLPA3005的spi控制

Part Number: DLPC6540
Other Parts Discussed in Thread: DLPA3005, DLP471TP

我们在使用基于DLPC6540+DLPA3005+DLP471TP的方案。但是目前在主板启动时发现当DLPC6540往DLPA3005发送一批SPI命令后,INT_Z就被置有效从而导致主板关机。

使用逻辑分析仪抓取了启动瞬间发送的spi命令如下:

看了一下DLPA3005的datasheet,里面的Register Map只列了地址00~08,实际发送的命令里除了这些地址还有其他地址,这些寄存器读写数据的意义是什么?具体是什么引起DLPA3005报错?
