power_down model interrupt

[1751445591]

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 interrput disable wake up the PWOER_DOWN , and  the third PIN interrupt also   entery  interrpution 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

Hi lin ya,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
I'm afraid it's impossible to enter interrupt function however MCU still in the low power mode.
Have a great day,
TIC
