The module provides the regulated supply voltage for the SIM-card and the circuitry to detect the insertion
or extraction of the SIM-Card in or from the mobile.
When the SIM-card is inserted, a mechanical contact connected on the module terminal is tripped and
after debouncing, an interrupt is generated. The SIM-card presence detection logic must be active even
when the system is in idle mode. Thus, the debouncing logic is based on the 32 kHz low-activity clock.
