Table 10: Pin Definition of (U)SIM Interfaces
EM120R-GL&EM160R-GL support (U)SIM card hot-plug via the USIM_DET pin, which is a level trigger
pin. The USIM_DET is normally short-circuited to ground when (U)SIM card is not inserted. When the
(U)SIM card is inserted, the USIM_DET will change from low to high level. The rising edge will indicate
insertion of the (U)SIM card. When the (U)SIM card is removed, the USIM_DET will change from high to
low level. This falling edge will indicate the absence of the (U)SIM card.
