Configuration

30 G24/H24 - Developer’s Kit August 31, 2009

The S100 switches description and functionality are shown in Table 2-15.

Note: Generally, your application wakes up the G24/H24. In cases where the application is not

ready for integration, you can force wakeup of the G24/H24 by setting the switch to ON.

SIM Card

The SIM card connector (J100) is external to the G24/H24, but is connected directly to it, similar

to an internal SIM. The G24/H24 can accept 3V SIM cards. The SIM Connector pinout (J100) is

shown in Table 2-17.

G24/H24 detects the presence of the SIM card through the SIM_PD signal. This signal is

configured in the G24/H24 as Active-Low.
