FOR S32K388,
Configured CM7_CORE_CLK = 320 MHz and Core_CLK is 160 Mhz.
What are these clocks and which clock frequency is used for Core?, (CM7_CORE_CLOCK or Core_Clock)
Where is the other frequency is used?
if we measure the cycle time with this configuration what is the frequency we will get?
What are the settings required for maximum operational frequency of 320 MHz?
Hello @Sambasiva,
Refer to Figure 11. Block diagram – S32K389 in S32K3xx RM, Rev. 12, 2025-11-11.
CORE_CLK is the system clock.
While CM7_CORE_CLK is the clock of the CM7 cores.
All the clocks must be configured precisely according to Table 153. Option A++ - Very High Performance mode (CM7_CORE_CLK @ 320 MHz) (For S32K388/S32K389).
Regards,
Daniel
Thanks for the Details.
After setting the clock, For verifying the clock for the Peripheral registers i could able to See only the Source used as input and the Divider value for deriving the Clock.
Also, I have seen Mcu_GetClockFrequency() Integrface, With this can i able to measure the Clock directly? After Mcu initialization?
Could you please suggest the mechanism to check the exact clock configured for Core and System clocks.
