hi , we have a reader that can read all nfc tag ,it also can read the share memory of 3100,at that same time ,we can also write data to 3100 share memory through 1443 protocol .

but 3100 didn't reply as Android phone even though we write the same data to share memory .

from the firmware code ,we can judge the nfc register ,but we really do not know why the register change .

can you also tell me the flow of the register value change when write data to nfc share memory ?
