This program shows LP0/LP1 wake-up times indicated by GPIO toggles.

Example functionality:
    - LP0 and LP1 both wake up to LP3 (run mode).

    1. LED3 blinks on program start.  - LP3
    2. Press SW3(P60) to begin. (LED3 on, other LEDs off) - LP3
    3. Press SW2(P55) to enter LP1. (LED1 on, other LEDs off) - LP1
    4. Press SW2(P55) to wake-up from LP1. (LED3 on, other LEDs off) - LP3
    5. Press SW1(P54) to enter LP0. (LED0 on, other LEDs off) - LP0
    6. Press SW1(P54) to wake-up from LP0 and restart program. (LED3 blinking) - LP3
       - To measure wake-up times
       - LP1 Wake-up - measure from falling edge of P5.5 to falling edge of P0.7
       - LP0 Wake-up - measure from falling edge of P5.4 to falling edge of P0.7

Debugging Note:
    The JTAG debug interface is disabled in LP0 mode and will result
    in the debugger losing connection to the MAX32630 when the part enters LP0.
    It is recommended that debugging is done prior to entering LP0 and then
    disconnecting the IDE from the debug session prior to entering LP0.
