PN5180, Can't activate type A NFC card

Hi, I'm trying to emulate an NFC type A card reader using the PN5180. with a host (PSoC 4). I'm following the MF0ICU1 document. As I understand, on its chapter 7.6, I'm doing the next:


1- Load config

2- Disable crc_rx

3- Disable crc_tx

4- Activate rf

5- Send REQA

6- Read ATQA


Everything ok till step 6 (I have checked the registers I have modified) but RX buffer still void so I don't receive any ATQA data.  Any idea where the problem can come from?


Thanks a lot!
