I want to design a S32k144 board with no external crystal or clock. Is it possible?
The point is that in processor expert under clock sources, for SPLL_CLK I can only choose SOSC as reference.
Or am I missing some thing?
Please see Figure 26-1 in the Reference Manual.
Only OSC can be used as a clock source for PLL.
Without OSC, you need to use FIRC or SIRC directly.
