AM4376: Power domain control

Nomo

Part Number: AM4376

Hello,

Can ON/OFF of the following power domains be controlled by the user?
- PD_MPU_EMU
- PD_PER_PLL
- PD_DISP_PLL
- PD_CORE_PLL
- PD_DDR_PLL
- PD_MPU_DPLL

I can find that the power domain of EFUSE, MPU, GFX, PER can be switched by PM_<Power domain>_PWRSTCTRL[1:0] from TRM.
However, I cannot find the settings for the above power domains.

Best Regards,

Nomo

Hi Nomo,

Regarding PD_MPU_EMU, I can not find register that can control its switch, thus I think this power domain can not be controlled by the user. Same as PD_EMU.

Regarding PD_CORE_PLL and other PLLs, you should use PRCM_CM_CLKMODE_DPLL_CORE[10] DPLL_LPMODE_EN

Pavel
