hello, everybody:


I have a question about CLRC663 how to transmit data with Miller coded but not NRZ in ISO14443B.

I saw that there are some description about data with miller coded.

It is in the 8.3.2 part ( ISO/IEC14443 type B functionality ) of datasheet (High performance multi-protocol NFC frontend CLRC663 and CLRC663 plus).

And I've seen three registers for miller encoding, 9.16.3 TxDataMod, 9.16.12 TxSym10Mod Reg, and 9.16.13 TxSym32Mod.

I tried to configure them as follows but it seems not to work.By the way, I using the RC663 without library.


Rc663_WriteRegister(CLRC663_REG_TXDATAMOD, 0x50);
Rc663_WriteRegister(CLRC663_REG_TXSYM10MOD, 0x50);
Rc663_WriteRegister(CLRC663_REG_TXSYM32MOD, 0x50);


So, I miss anything in the configuration or I configured it wrong.?

If it were possible to configure Miller coding in ISO14443B using CLRC663?
