Tool/software:
Hi,
My customer has below questions for PMIC_LPM_EN0 signal connected to TPS6521902 MODE/STBY.
Please answer them.
Q1) The customer understood PMIC_LPM_EN0 goes to Low when AM62x enters low power mode, then the signal goes to High on wake-up.
There are a few low power modes in AM62x. With which low power mode(s), the signal is used?
Q2) The customer wants to know exact sequence when the signal is switched.
Do you have waveform and state transition diagram, etc.?
Q3) How the signal is configured in Linux SDK?
For example, can we configure the signal is not used for DeepSleep?
Q4) Can we use GPIO instead of PMIC_LPM_EN0?
If Yes, when the signal should be driven to low and high?
Q5) The customer wants document which explains PMIC_LPM_EN0 function in details.
Thanks and regards,
Koichiro Tashiro
