about IRQ pin in X-NUCLEO-NFC06A1

[DSai.1]

Dear Sir,

When I read the document of X-NUCLEO-NFC06A1, I found that the IRQ pin is not

connected to CN5. I wonder the demo sample provided in

ST25NFC_Embedded_Lib_ST25R3916_1.4.0\Projects\STM32L476RG-Nucleo\Applications\X-NUCLEO-NFC06A1 do not use IRQ interrupt?

best regards

Hi,

IRQ_MCU is by default routed to CN8.1.

CN5.2 is only an alternate routing (ST9 is open in the factory configuration).

See Table 1 in UM2615.

ST25NFC_Embedded_Lib_ST25R3916_1.4.0\Projects\STM32L476RG-Nucleo\Applications\X-NUCLEO-NFC06A1 uses IRQ_MCU on CN8.1/PA0
