Anyone can enable clk_aux output for TDA in PN7462?
Thanks in advance
NXP confirm that the PN7362 don't have ISO7816 digital UART for that SAM can only de used with 7462.
Thanks Dennis is working now in the PN7462 . But not in the PN7362 do you know if this chip support auxiliar slot ?
Hello Sergio,
did you set the IOAUXen and CLKAUXen bit in the CT_SSR_REG ?
additional i had to set the SLEW_RATE to 1 in the PCR_PAD_CLK_AUX_REG because the clock signal looks too bad at the input at the tda8026. now i'm able to read the ATR from a smart card.
Hi Dennis,
How did you manage to activate the card? Have you had no problem reading ATR?
Clock output works - thanks, but with ATR reading it failed :-(.

Anyone had some example that work ?.

Hello,
i've got the same question and i doesn't find the answer in UM10858 from the PN7462 Controller Development Kit and now i'm waiting to get access to UM314511 to solve the problem.
Hello Sergio,
Please refer to Um314511 - UM10858 PN7462 HW User Manual (1.1) available under NDA in DocStore for more information about enabling CLK_AUX for TDA slot extender.
I hope this helps.
Best regards,
Ivan.
