anybody is there who works on MCBSTR9 Evaluation Board

OK I finally got it.

Here is the solution:

//P3 configuration

SCU->GPIOOUT[3] &= 0xC3FF;
GPIO3->DDR &= 0x9F;

//WIU (AND SCU!!!) configuration
//Hey, I didn't did this before!!!!

SCU->PCGR1 |= 0x00002000;
SCU->PRR1 |= 0x00002000;

WIU->MR |= ~0x00000003;
WIU->CTRL |= 0x00000002;

SCU->WKUPSEL |= 0x00000005;

//VIC configuration

VIC1->VAiR[10] = (unsigned int)Switch_IRQ_Handler;
VIC1->VCiR[10] |= 0x20;
VIC1->VCiR[10] |= 10;
VIC1->INTER |= (1<<10);

And that's all to generate external interrupt by S2 (or other WIU sources).

Don't forget to acknowledge the interrupt in handler function and to clear EXTINT5 bit (WIU->PR |= 0x00000020;)

You can also work with ST librarys if you don't like to work at bit level. They got smart functions that do it for you.

Bye!
