Hello. My customer has used i.MX 6Dual and PF0100.
PF0100's VSNVS output starts from 1.0 V when LICELL is valid before VIN.
*Refer to "Figure 6. Default start-up sequence" in MMPF0100Z(Rev.10).
And, the VSNVS output to external oscillator (32.768kHz), too.
But, the oscillator started the operation at 1V.
The Osc clock has been inputted to i.MX6 with power off.
(VDD_SNVS_CAP was 0V. So internal LDO looks disabled.)
*Refer to attached system structure.
Does the Osc clock give i.MX damage during above situation?
(Or, is there possibility to destroy the i.MX6 device?)
Amplitude of osc clock was measured 1.1V.
