PN532 I2C IRQ pin
I'd connected the PN532 break-out board via I2C to an Atmel controller.
Is the IRQ pin absolutely required to communicate with the PN532 via I2C?
Can the IRQ pin left unconnected?
I understand the the PN532 Application Note v1.2 that the PN532 gets into "normal mode" by default (with P35 being connected to VDD internally, and with IRQ pin being either low or high).
