2.current consumption--電流消耗

    standby mode --待機模式

3.IIR(Infinite Impulse Response)  無限脈衝響應數字濾波器

ami_sint8 AMI_SetIIRStrength(ami_uint8 MF, ami_uint8 GF); 用於設定M-sensor和M-sensor的IIR

4.LDO是low dropout regulator

     意為低壓差 線性穩壓器，是相對於傳統的線性穩壓器來說的。傳統的線性穩壓器，如78xx系列的晶片都要求輸入電壓要比輸出電壓高出2v~3V以上，否則就不能正常工作。但是在一些情況下，這樣的條件顯然是太苛刻了，如5v轉3.3v,輸入與輸出的壓差只有1.7v，顯然是不滿足條件的。針對這種情況，才有了LDO類的電源轉換晶片。
5.ADI是Analog-Die Interface

如kernel/arch/arm/mach-sc8810/include/mach/adi_hal_internal.h

ADI_Analogdie_reg_write(reg_addr, (unsigned short)(value))

ADI_Analogdie_reg_read(reg_addr)

 die的語義：A die in
the context of integrated circuits is a
small block of semiconducting material,
on which a given functional circuit is fabricated. Typically, integrated circuits are produced in large batches on a single wafer of
electronic-grade silicon (EGS) or other
semiconductor (such as GaAs) through processes
such as photolithography. The wafer is
cut (“diced”) into many pieces, each containing one copy of the circuit. Each of these pieces is called a die.

There are three commonly used plural forms: dice, dies, and die.
