HI,
I read all registers by spi , found the miso pin is always low, then i write register 0x09 , value 0x01, and then read the register, the miso is low。
I found a strange problem, When I lower the cs pin, the mios pin will also be pulled down, When I pull up the cs pin, the mios pin will also be pulled up,
But the data in between has always been zero。
