DIX9211设定

请问DIX9211设定地址31h,32h,33h XTI Source, Clock (SCK/BCK/LRCK) Frequency Setting，是输入还是输出的设定?

Guoliang Li：

An external clock source (CMOS or crystal/resonator) is known as the XTI source. The XTI source can be eithera CMOS logic source, or a crystal resonator .

When the PLL is locked, the secondary clock source automatically selects the PLL clock (256fS). Otherwise, theXTI clock source is selected. Register 32h should be used for dividing in the lock status (that is, the PLL source).When unlocked, Register 33h should be used (the XTI source).

 XTI 是外部时钟的输入pin,通过31h, 32h,33h 寄存器设置外部时钟XTI的分频因子等。31h, 32h,33h 寄存器本身可读也可以写。
