Note
: The resistor value on SIMIO pulled up to SIMVCC should be
defined accordingly in order to be compliant with 3GPP specification.
LE910Cx-mPCIe contains an internal pull-up resistor on SIMIO.
However, the un-mounted option in the application design can be
recommended in order to tune R1 if necessary.
