Power on Sequence

SIM5215&SIM5216 can be powered on by POWER_ON pin, which starts normal operating mode.
POWER_ON pin is pulled up with a 200kR resistor to 1.8V in module. User can power on the
SIM5215&SIM5216 by pulling the POWER_ON pin down for a short time. The power-on scenarios are
illustrated in the following figures.
