Hello,

With the pn512, it was possible to manual fine tuning the internal receiver 
through eeprom settings (cf user manual 
http://www.nxp.com/documents/data_sheet/PN512.pdf), and in particular, 
automatic parity generation could be switched off using the ManualRCVReg 
register’s ParityDisable bit.
With the pn53x, it was possible too by writing 0x10 at the eeprom address 
0x630D (http://www.nxp.com/documents/user_manual/157830_PN533_um080103.pdf)

It was also possible to switch off the automatic CRC generation.

With the PN544, I saw that the chip is also tuned through its eeprom but I 
can't find if the parity/CRC tuning is still possible... Where can I find 
the PN544 user manual with all the eeprom instructions set ?

Tahnk you in advance

Grégoire
