Hi Expert,

For the configuration of NXP_EXT_TVDD_CFG_1={20, 02, 07, 01, A0, 0E, 03, 02, 09, 00} & NXP_EXT_TVDD_CFG_2={20, 02, 07, 01, A0, 0E, 03, 06, 64, 00} in libnfc-nxp.conf.

Could you describe the content mean in NXP_EXT_TVDD_CFG_1 & NXP_EXT_TVDD_CFG_2,

or share me the documents of their description.

 

Thanks.

Br,

Michael Chen
