你好，
我是用DVRDK 4.0， 从内核的code中看到如下的定义：
/* TI81XX mux mode options for each pin.Go through TRM/DataSheet for details */
#define TI81XX_MUX_MODE0 0
#define TI81XX_MUX_MODE1 1
#define TI81XX_MUX_MODE2 2
#define TI81XX_MUX_MODE3 3
#define TI81XX_MUX_MODE4 4
#define TI81XX_MUX_MODE5 5
#define TI81XX_MUX_MODE6 6
#define TI81XX_MUX_MODE7 7
#define TI81XX_MUX_MODE8 8
#define TI81XX_MUX_MODE9 9
#define TI81XX_MUX_MODE10 10
#define TI81XX_MUX_MODE11 11
/* TI816x Specific mux bit definitions */
#define TI816X_PULL_DIS (1 << 3)
#define TI816X_PULL_UP (1 << 4)
这些定义代表的PIN mux的功能说明哪里可以找到呢？上面的TRM/datasheet是什么文件呢？
谢谢
