Tamper (tamper)

+//! +//! An example to demonstrate the use of tamper function in Hibernate module. +//! The user can ground any of these four GPIO pins(PM4, PM5, PM6, PM7 on +//! J28 and J30 headers on the development kit) to manually +//! triggle tamper events(s). The red indicators on the top of display should +//! reflect on which pin has triggered a tamper event. +//! The event along with the time stamp will be printed on the display. +//! The user can put the system in hibernation by pressing the HIB button. +//! The system should wake when the user either press RESET button, +//! or ground any of the four pins to trigger tamper event(s). When the +//! system boots up, the display should show whether the system woke +//! from hibernation or booted up from POR in which case a description of +//! howto instruction is printed on the display. +//! The RTC clock is displayed on the bottom of the display, the clock starts +//! from August 1st, 2013 at midnight when the app starts. The date and time +//! can be changed by pressing the CLOCK button. The clock is update every +//! second using hibernate calendar match interrupt. When the system +//! is in hibernation, the clock update on the display is paused, it resumes +//! once the system wakes up from hibernation. +//! +//! WARNING: XOSC failure is implemented in this example code, care must be +//! taken to ensure that the XOSCn pin(Y3) is properly grounded in order to +//! safely generate the external oscillator failure without damaging the +//! external oscillator. XOSCFAIL can be triggered as a tamper event, +//! as well as wakeup event from hibernation. +// +//***************************************************************************** + +//***************************************************************************** +// +// Global variables used for Tamper events. +// +//***************************************************************************** +static volatile uint32_t g_ui32NMIEvent = 0;
