// Application: Power Down Wake up
// External interrupt 0 Wake up => P1.3 input low(falling edge).
// External interrupt 1 Wake up => P1.4 input low(falling edge).
// Keyboard interrupt Wake up => P0 input low(falling edge)
// Brown out interrupt Wake up => Vdd < 3.8V
// Watch dog interrupt Wake up => Watch dog timer time out
// ADC interrupt Wake up => ADC conversion finish
//
// Output : UART show result on hyper-terminal
// P1.7 toggle when MCU wake up every once
// P1.4 flash when power down pass
// P2.1 flash when power down pass
