Hello to TI engineers, I met a problem. I based on CC1100 manual startup sequence, pulled down the CSn, and then pulled up keeping it above 40us, and then pulled the CSn to the bottom. But there was no CHIP_RDYn signals on MISO. The sequence that I grab is as shown in figure. What is more, when I went to read the value of the register, it was 0xf. Here is its datasheet http://www.kynix.com/Detail/120152/CC110…. I don’t know why. Who can explain for me，please~ Thank you！
This type of question is beyond the scope of iFixit, which is for helping folks fix stuff themselves. What the OP is asking for goes deep into the realm of electronics design. I would suggest the question be made on Stack Exchange instead. @theimedic
