About int18 in sample code spc58ec wkpu

[tuananh13]

Hello, I have a question. Regarding waking up the system from LOW POWER mode, I want to use the WKPU but not with a push button as in the example.  Instead, I want to use a GPIO port to monitor an external signal. I want to use a rising edge interrupt. I cannot use INT18 because it is connected to a push button and the signal pin is always connected to VCC.  Therefore, a rising edge cannot be achieved.

Hello Tuan,

I recommend to check SPC5Studio Tools Suite

SPC5-STUDIO - Code Generator, Quick resources configurator and Eclipse development environment for SPC5 MCUs - STMicroelectronics

Which family do you use?
