Where to find the response data of a CLRC663?

[ME1234]

I have an NTAG5 connected to an CLEV6630B DevBoard. After sending an Read SRAM command (0xD2) I got a card response 0x73, which is pretty fine. I could see the response data in the "Tag communication" tag of the NXP-NFC cockpit under "Card Response".  Up to there I am satisfied. Know I want to read the responsed data directly.

In which register of the CLRC663 could I find the received data? I hope to find them in FIFODATA_REG, but there I only could read 0x00 instead of the expected 0x73.
