SPI can use. Write the register as Example 4. But the DRDY I/O always high, and the OPSTAT register(0x1F) is 0x0004. Read by the frames mode(0x40), the Frame Header is 0xC0000. All the Ready bit is 1.Write the register as Example 1. The status is also like Example 1.
Is there any operation I should do after reset the chip? Why it always be busy?
