We want to reducy harmonic,
and we change the GSN to 0x02 in CLIF_ANA_TX_AMPLITUDE_REG
We use NfcrdlibEx1_BasicDiscoveryLoop exmaple.
from 0xFFFFxxxx to 0x02FFxxxx (there are 27 values)
from 0xFFFFxxxx to 0x02FFxxxx before call phacDiscLoop_Run()
The CLIF_ANA_TX_AMPLITUDE_REG become 0xFFFFxxxx automatically, I can not found when the SDK access CLIF_ANA_TX_AMPLITUDE_REG from source code.
Does the CLIF_ANA_TX_AMPLITUDE_REG access inside the library?
How to reduce the Tx power?
Or any suggestion about hardware?
Hi tein Su,
How did you generate the user_EE.bin? Did you follow the steps described in https://www.nxp.com/docs/en/user-guide/UM10948.pdf ? If yes, is it possible to send the "_output_xml_sizes.html" for a review?
Thanks for your patience!
Have a great day,
Kan

I will try to ask the customer to provide "_output_xml_sizes.html" file
and do you have any idea can solve harmonic issue?
thanks!

Hi Tein,
From my understanding, this issue is related with the EMC design, and we have a training for that topic , you may refer to NFC Antenna Design 6: EMC related Design|NXP for details.
Hope that helps,
Have a great day,
Kan
