[INT_SYS_DisableIRQGlobal ] API can not disable IRQ

When I try to sleep into VLPS mode for operation, and call the INT_SYS_DisableIRQGlobal want to close all interrupt, but it doesn't work, quickly awakened the VLPS mode, only one by one manually shut down I open interrupt

Hello, 

which S32DS and SDK version you are using (I'm assuming that your device is S32K144) ?

Thank you for your reply

I try to use the INT_SYS_DisableIRQGlobal API in other projects, that can turn off the serial port interrupt, serial port will not send data, I estimate the VLPS model quickly wake up, because although the interrupt is closed, but there is still such interrupt source, trigger interrupt?

Hi, 

the INT_SYS_DasableIRQGlobal() is working as expected - all interrupts are disabled. Did you also turned OFF PLL by software? As mentioned on reference manual (chapter 25.4.4 - page 522).
