2.5.2 SIM1 Interface
This interface can be used as a second SIM interface for GM02S, typically used
for soldered SIM chips (since it lacks SIM detect and SIM VCC). If design only
has one SIM, it is preferred then to use the main SIM interface (see Section
SIM0 Interface above).
Note: See Section 2.3 Power on page 6 for behavior of IOs in Deep Sleep
mode.
