NFC reader lib + CLRC66302 in single ended mode

[ddalfra]

Hi All

We're working on a LPC1768 and CLRC66302 by using NXP NFCrdlib. So far the porting has gone well.
In our hardware the frontend (CLRC66302) is used in single-ended  and i need to change some register setting, in particular:

1. Rcv register (address 38h)
2. TxAmp register (address 29h)
3. TxCon register (address 2Ah)

My question is: where's the right place inside NFCrdlib to do that according to the values i need?
I'm working with ISO15693 tags.

Thanks in advance
