你好，我使用的是PIC32 MX795F512L和M25P16 SPI闪存。时钟被拉下来，MISO通过10K电阻被拉起来。我写的是“读ID命令＝0x9F”，然后跟着20个虚拟时钟周期读取MISO引脚上的数据。我用的是SPI3，CLock模式是Clock 3（CPOL=1，CPHA=1），波特率是1MHz。问题是闪光灯响应是可预测的，如所附波形图所示。硬件设计有什么问题吗？还是我用错误的方式编程？

Hi,
I am using the PIC32MX795F512L with M25P16 SPI Flash. The Clock is pulled down and MISO is pulled up via 10k resistor. I was wri
ting the 'Read ID command = 0x9f' and then followed by 20 dummy clock cycle to read data on MISO pin. I'm using SPI3, CLock mode is Clock 3 (CPOL = 1, CPHA = 1) and baudrate is 1MHz.
The problem is response by flash is up predictable as shown in attached waveform image.
Is there anything wrong with hardware design? Or am I programming it in wrong way?
