Hi Sir/ Madam,
I am developing Pass-Through for NXP NTAG I2C 1K application (Datasheet NT3H1101_1201.pdf).
I am struggling how to configure or write Pass-Through ( Bit #6 in NC_REG, inside session register). I have try to write it, but it still remain as "0" when read back. May I know what is the appropriate values of all the 7 register in session register, in order to be able to write a "1" into Bit #6 of NC_REG, of Session Register ?
I do feel that there are certain bits and registers have to be configure first before this Bit #6 is able to be written.
For example, Bit #6 (I2C_LOCKED) of NS_REG, will be automatically set when Register WDT is written 0xFF.
I have tried out many experiment to get this work, but still I am not able to get the result.
Please help soon.
Thank you for your advice.
Cheers,
KF Choong
Hello KF Choong,
The Pass-through mode bit (PTHRU_ON_OFF) can only be enabled when both interfaces (I2C and NFC) are ON. Soif there is not a field from an Active NFC Reader over the antenna of the NTAG I2C device, the bit will automatically reset to 0.
I hope this clarifies.
Regards!
