7Overview
8********
9
10This sample can be used for basic power measurement and as an example of
11soft off on NXP i.MX RT platforms. The functional behavior is:
12
13* Busy-wait for 2 seconds
14* Turn the system off after enabling wakeup through a button press, and
15  additionally set an alarm 10 seconds in the future to wake up the processor
16
17A power monitor will be able to distinguish among these states.

351. Open UART terminal.
362. Power Cycle Device.
373. Device will turn on and idle for 2 seconds
384. Device will turn itself off using deep sleep state 1. Press SW 5
39   to wake the device and restart the application as if it had been
40   powered back on. Alternatively, wait 10 seconds for the SNVS RTC
41   alarm to fire and wake the device up automatically.
