关于TMS320F28069的问题

ruiping,
1<<0, 表示1左移0位，
1<<1 表示左移1位。
这些是用在寄存器配置。

1 << 0：对bit0置1；

1 << 1：对bit1置1；（1左移1位）

麻烦再追问一下，在头文件中有
//! brief Defines the number of bits per INTSELxNy register //! #define ADC_INTSELxNy_NUMBITS_PER_REG 8
//! brief Defines the log2() of the number of bits per INTSELxNy register //! #define ADC_INTSELxNy_LOG2_NUMBITS_PER_REG 3
//! brief Defines the location of the INTSEL bits in the INTSELxNy register //! #define ADC_INTSELxNy_INTSEL_BITS (31 << 0)

8在这里如何解释， (15 << 6)如何解释，是15位左移6位吗， (31 << 11)，寄存器是最多32位吗，31位左移11位后变成什么了，不就又回到低位了？
谢谢

31=0x1F，左移11位为0xF800.对应着ADCSOCxCTL的TRIGSEL所在的高五位

谢谢啦
