Dear

Dear NXP team,

I'm trying to send signal to LOADMOD pin. I'm changing CIU_TxSel register to 0b01010000. But I cannot see any signal at LOADMOD pin.
Please give me advice, what registers should I change so I can see a signal from internal coder at LOADMOD. My PN532 is working in "PN532_COMMAND_TGINITASTARGET" mode.

BR, Andrey.

Hello,

Please refer to Fig 40. Serial data switch for LOADMOD pin in the data-sheet:

https://www.nxp.com/docs/en/nxp/data-sheets/PN532_C1.pdf 

Depending on LoadModSel, you will have some signals  to be output on LOADMOD. Please refer to chapter 8.6.23.22 CIU_TxSel register (6306h) for more information.

Regards,

Ivan.
