RUIM (SIM CAR)

RH-27 supports RUIM for China products. The following waveform can be used to verify
that sim_vcc; sim_i/o, sim_clk, and sim_rst signals are activated in the correct sequence
at power up. This picture can be taken when the RUIM is installed on the phone and
measures the signals when the phone is turned on. The following picture shows the
proper waveforms when the interface is working. See "Bottom view" diagram for the test
