2.5.1. UIMx_DET

UIMx_DET is used to detect and notify the application about the insertion and removal of a UIM

device in the UIM socket connected to the UIM interface (UIM1 or UIM2). When a UIM is inserted, the

state of UIMx_DET transitions from logic 0 to logic 1. Inversely, when a UIM is removed, the state of

UIM1_DET transitions from logic 1 to logic 0.

The GPIO used for UIM1_DET is GPIO3, and the GPIO used for UIM2_DET is GPIO4.
