Hi, I am using MPC5748G watchdog module.And how to config system clock: MC_ME.GS.B.S_SIRCON=1?

Here is my code,and the project can not work OK.

void SWT_enable(void)

{

SWT_0.SR.R=0xc520;

SWT_0.SR.R=0xd928;

SWT_0.TO.R=2560000; //10s

SWT_0.CR.R=0x8000010B;

}

void SWT_service(void)

{

SWT_0.SR.B.WSC=0xA602;

SWT_0.SR.B.WSC=0xB480;

}

Hello,

Please see reference examples for clock configuration we have posted on community:

Follow the clock configuration in those examples and I am sure you won't have any issues.

SWT init and SWT service looks good.

Peter

PS: don't forget that our examples use 40MHz XTAL.
