Hi,

 

i want to set the LPO32K_CLOCK as wdog clock source

Settings:

 

 

PMC->REGSC = PMC_REGSC_LPODIS(0);    /* 0b - Low power oscillator enabled */

 

SIM->LPOCLKS = SIM_LPOCLKS_LPOCLKSEL(2);    /* LPO32K_CLK Source */

 

 WDOG->CS = WDOG_CS_CLK(1)    /* Watchdog Clock --> 1b - LPO Clock */

 

 

 

This seetings shout normaly enable the 32 KHz LPO clock, but if i measure it, it seems to use still the 128 KHz LPO...

 

 

regards,

Adrian
