• ON – Strong PULL-UP resistors will be applied to eMMC CMD (blue) and DATA (green) lines. This is very useful feature for phones that require VccQ and Vcc power connections (Samsung, HTC, etc.)
• OFF – PULL-UP resistors WILL NOT be used. This is normally done with Nokia Lumia phones which do not require VccQ and Vcc connections for a more stable link, set switch to “ON” and make sure to connect required power to VccQ and Vcc lines. ATF V3 Adapter Best Price in Pakistan

• NC – Secondary CLOCK will not be used for eMMC communication*
• CLK2 – Secondary CLOCK will be used for eMMC Communication

*When adapter is used for a NON-EMMC connection such as JTAG or Micro SD card, make sure that DIP switch is set on the “NC” position.
“CLK2” is NOT REQUIRED for most eMMC chips, but setting DIP switch to “CLK2” will give you a stronger CLK (red) signal for better eMMC communication.
