hello !

use LPC824 33PIN MCU .The Programs maked the MCU into POWER_DOWN model, the programs also set PO-04 for PIN interrupt third port. Set the PO-04 for falling edge and port interrupt enabled,but the interrupt disable wake up the POWER_DOWN . due to the third PIN interrupt only handle the interrupt inside programs for pulse counting.and the external pulse is frequently . therefore hope when the MCU into the POWER_DOWN ,the third PIN interrupt disable wake up the Power_DOWN , and the third PIN interrupt also entry interrupt when external pulse trigger .I try but the hope is not success ,the third PIN interrupt is not entered . Why is it ?I need your help ! thinks
