Significance of the different run modes for "VDD_SOC_IN" ? Found for i.MX6UL

[wowa]

Dear Community,

i found some informations in the Datasheet "IMX6ULCEC" under the operating ranges about the input voltages of "VDD_SOC_IN".

Could anyone explain the difference between the Run Modes "LDO enabled", "LDO bypassed" and "Suspend (DSM) Mode" ?

I could not find something in the datasheet or reference manual. And what mode is the standard mode ?

Thanks beforehand for your efforts.

BR

Hi Walter

Figure 1 i.MX 6UltraLite power rails AN5170 i.MX 6 UltraLite Power Consumption

Measurement shows processor power design. "LDO enabled", standard mode

when core is powered from internal LDO. "LDO bypassed" when LDO is shorted:

VDD_ARM_CAP=VDD_SOC_IN.

DSM is described in sect.4.1.1. Use case 1: Deep-Sleep mode (DSM)
