PN7150 ATS TA(1) customization

albertobattistello — Fri, 06 May 2022 15:50:13 GMT

Hi,

I am not able to change the value of the most significant bit of the 3rd byte of ATS (msb of TA(1) of ATS) in the PN7150 by using the NxpNci lib. I would like to reset it ('0') in order to enable "different divisors".

Is there a way to change such value? Or is it hardcoded?

Regards,

Alberto

Hi Alberto:

In card emulation mode we only support same Baudrate.

This is from NCI 1.0 (PN7150). PN7150 supports 106, 212, 424, 848kbit/s , but with TA(1), we don't support change the baudrate, for example, 106kbit/s on card mode and 212kbit/s on reader and this is not supported on card emulation mode.

Regards

Daniel
