1. SIM_DATA pull-up resistor
2. Use under 33pF (Cap_Varistor) on each signal line
3. When routing, SIM_DATA, SIM_CLK should be seperated
4. CAP,Varistor should Place close to connector

Note 1. +2V95_SD_PULL_UP ( 1.8 or 2.95V ) switches automatically per inserted SD Card version
For example, SD card Version 2.0 = 2.95V, Version 3.0 = 1.8V
Note 2. +2V95_SD_VCC is SD/MMC Power

MC-C04582-14 : Below items should be satisfied
1. SD_DETECT Pull-up or Pull-down
2. Data/CMD line should be needed Pull-up resistor
( If chipset has internal Pull-up, comment it on circuit )
3. Use under total 10pF Capacitance on each line ; Data [0:3], CMD - Cap. TVS diode, varistor
( on other line, We recommend 10pF capacitance and use under 30pF capacitance )
4. CAP,Varistor should Place close to connector
(DGMS Guide)
MC-C05446-7 : Below items should be satisfied
1. Power of SD card should use independant Power source just like LDO/PMIC which can turn off it.
2. Per chip type which support SD card should manage current capacity.
( In case of High speed mode, SD Card Power should get margin of 200mA )
3. Do not connect serial component to SD card power, voltage drop can arise at Power line.

Caution ! - According to MSM8960, APQ8064 BackPowering issue, +2V95_SD_PULL_UP was Always on during sleep mode.
However, It is possible for MSM8974, MSM8x10 .. to be turned off, so, FET circuit to turn off it is not needed any more.
