I want to config FTM clock source,according this figure,I choose SYS_CLK as FTM clock.
In my codes,I config register so that work,
FTM0->MODE |= FTM_MODE_WPDIS_MASK;
FTM0->SC |= 0x00030008;
But when I use S32DS Debug find this register value Not equal to I write,
I refer <<S32K1xx Series Reference Manual, Rev. 7, 04/2018>> ，it describes these bits :
so why s32k144 was force to set CLKS as 11b? Is setting CLKS as 01b forbidden?
