哪位大侠可以帮我一下吗?在user.h头文件中如下定义:
//! \brief Defines the location of the HRPWMENCLK bits in the PCLKCR0 register
//!
#define CLK_PCLKCR0_HRPWMENCLK_BITS (1 << 0)
//! \brief Defines the location of the LINAENCLK bits in the PCLKCR0 register
//!
#define CLK_PCLKCR0_LINAENCLK_BITS (1 << 1)
中 (1 << 0),和 (1 << 1) 是什么意思??
谢谢啦

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)
//! \brief Defines the location of the INTE bits in the INTSELxNy register //! #define ADC_INTSELxNy_INTE_BITS (1 << 5)
//! \brief Defines the location of the INTCONT bits in the INTSELxNy register //! #define ADC_INTSELxNy_INTCONT_BITS (1 << 6)
//! \brief Defines the location of the ACQPS bits in the ADCSOCxCTL register //! #define ADC_ADCSOCxCTL_ACQPS_BITS (63 << 0)
//! \brief Defines the location of the CHSEL bits in the ADCSOCxCTL register //! #define ADC_ADCSOCxCTL_CHSEL_BITS (15 << 6)
//! \brief Defines the location of the TRIGSEL bits in the ADCSOCxCTL register //! #define ADC_ADCSOCxCTL_TRIGSEL_BITS (31 << 11)
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

请问这是对应哪个通道啊
