Why is PN5180 EEPROM data at address 0x11 not consistent?

From the PN5180 datasheet, we got the EEPROM data at address 0x10-0x11 are Production Version and read only

when we try to send the command to PN5180 (firmware v3.9) to

1.Multi Read 2 bytes at address 0x10-0x11-> PN5180 response 2bytes (0x09,0x03)  (Good)

2.Single Read 1 bytes at address 0x11 only -> PN5180 response 1 bytes 0x0A (Not Good)

3.Multi Read 2 bytes at address 0x11-0x12 -> PN5180 response 2 bytes (0x0A,0x09) (Not Good)

The value read at EEPROM address 0x11 is not consistent compared  (2)(3) with (1). Could NXP guys/anyone please advise and explain why there's the different value at address 0x11 in EEPROM of PN5180?

Thanks,

Hello,

It is a bug, I already corroborated it with NFC Cockpit. R&D is already aware of this. The fix will be launch in the next release.

Have a great day!

Regards,

Ivan.
