AIPS_ PLAT_ CLK and AIPS_ SLOW_ CLK

[shiqi_seventeen]

Hello Team

I am using S32K312,there are some questions abou CLOCK.

I have a few questions :

1. AIPS_ PLAT_ CLK and AIPS_ SLOW_ CLK ,What does  mean about them?

2. AIPS_ PLAT_ CLK and AIPS_ SLOW_ CLK  ,What is the difference or connection between them?

3. AIPS_ PLAT_ CLK and AIPS_ SLOW_ CLK, What peripherals are CLK used on, or how should I choose them as the clock source for peripherals?

Thanks

Hi

Please download S32K3xx MCU Family - Reference Manual and read the 24.6 Peripheral clocking and 24.3.8 S32K312 clock system diagram.

AIPS_PLAT_CLK (medium-speed peripheral clock) (MC_CGM.MUX_0_DC_1[DIV])
AIPS_SLOW_CLK (slow-speed peripheral clock) (MC_CGM.MUX_0_DC_2[DIV])

If you are using S32DS, S32 Configuration Tool may help you understand it better.
