Purpose of Peripheral Clock Enable in Power Module when Clock Configurations exist?

[himonkoch]

I have found this setting called Peripheral Clock Enable in the POWER Module, which looks like the following:

My question is: how does this setting work? Why does it exist when Clock Configuration from CLOCK Module enables the clocks anyway? How does it work differently?

Hi @himonkoch 

The POWER component can be used to configure different working modes. S32K3 has different working modes to adapt to different power consumption situations. For example, when you configure the clock, the default is RUN mode. This means that if your application does not have low power consumption requirements, you do not need to configure the POWER component.

Check section 3.6.2 (MCU Mode Management) of the User Manual for the S32K3 MCU Driver provided with the RTDs. This document provide details about the MCU driver (limitations, HW and SW requirements, usage, configurations, etc.)that might be useful to you. These can be found, for example: C:\NXP\SW32K3_RTD_R21-11_3.0.0_P07\eclipse\plugins\Mcu_TS_T40D34M30I0R0\doc.
