Power On
The ME910X1-mPCIe will automatically Power ON as soon as VBATT applies to the
module and W_DISABLE_N and PERST_N are HI. The module is ready for use after HW
power Up and SW initialization process completes. For this reason, it is impossible to
access ME910X1-PCIe during the initialization state.
As shown below the ME910X1-mPCIe becomes operational (in the Activation state) at
least 20 seconds after power is applied:
