Hi,
Currently our customer is doing an electrical test(noise test) on the TRF7960A custom board
and there is problem that the TRF7960A outputs IRQ signal continously without stopping.
When a noise(150KHz, 10V) is applied to the on the RFID cable, there is a continous IRQ signal (ON/OFF).
Even if the IRQ state is changed to OFF state from the MCU, IRQ signal starts again after 20 to 50us.
Please let us know if there is any know issue or pointers on this problem.
Regards
Prad
