Insert SIM card

The hardware of the SIM interface from the MADLinda (D300) to the SIM connector (X101) can be tested without SIM card. This leaves SIM connector (X101) contacts to be used as an measurement points.

When the power is switched on and if the BSI line (X100:2) is grounded by resistor (which happens automatically in service jig), all the used lines (VSIM, RST, CLK & DATA) rise up to 3V and/or 5V four times (SW tries to ask SIM card four times).

NOTE1: CHECK THE MEASUREMENT POINT PICTURE BEFORE SERVICE ACTIONS

SIM_xxx_Cardside - refers to signal which exists in SIM card contacts

SIM_xxx_o - refers to signal which exists in CCONT(N100) side

NOTE2: SIM Signals between CCONT (N100) and LindaMAD (D300) are not possible to measure in KL8-module because traces are running in inner layers of PWB.
