IIS 模块的结构图，SCK、WS和SD分别是 IIS 的三根信号线，SCK 是驱动时钟，
WS是字选择信号，SD 是数据。SCK 由总线时钟分频而来，分频比可配。WS是占空比为
50％的周期性信号，高低电平分别对应左右（或者右左）声道，周期长度和音频数据的字长
有关。IIS 的数据（SD 信号）的变化比字选择（WS）晚一个时钟。IIS 支持8 位、16位、
32位字传输，数据的传输支持 DMA模式。在单声道模式下，左右声道输出同样的数据。 -IIS module structure, SCK, WS and SD were the three pillars IIS signal, SCK is driving a clock,
WS is word selection signal, SD is data. SCK clock points by bus and frequency, points frequency than can match. WS for empty than for
50 of periodic signal, high and low level corresponding around (or right left) track, the period length and audio data word length
Relevant. IIS data (SD signal) than word choice of change (WS) late a clock. IIS support eight, 16,
32 bit word transmission, the data transmission support DMA mode. In a single mode, or so the same data to the output channel.
