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
