DM3730寄存器配置

Other Parts Discussed in Thread: DM3730

在用DM3730数据手册中,有些疑问:

1.CBP,CBC和CUS代表什么意思呢?BALL BOTTOM 和BALL TOP是什么意思呢

2.引脚的mod如何选择呢?比如BALL BOTTOM的AB3引脚当MOD=0时为mcspi1_clk,当MOD=1时为mmc2_dat4。是不是通过控制寄存器来改变MOD的值,要是的话,MOD寄存器在哪里,地址是多少呢?

谢谢

  • 1.   手册中很容易就能搜到这代表不同的封装。    ball top/bottom也是能搜到的。这里我就不写了。

  • 关于MOD,在手册 2.3 Ball Characteristics 中描述:

    NOTE
    In the DM3730/25 device, new Far End load Settings registers are added for some IOs. This
    new feature configures the IO according to the transmission line and the
    application/peripheral load. For a full description on these registers, see the System Control
    Module / SCM Functional Description / Functional Register Description / Signal Integrity
    Parameter Control Registers with Pad Group Assignment section of the AM/DM37x
    Multimedia Device Technical Reference Manual (literature number SPRUGN4).

  • 你好,能否加个QQ,或者我的QQ343921227,我现在在研究DM3730+TVP515发现挺有意思的,但有些问题,所以想请教。我非常敬仰TI和TI的员工。
