系统延时函数

/*


void R_BSP_SoftwareDelay (uint32_t delay, bsp_delay_units_t units)
delay:时间数量
units:时间单位
*/

可选的时间单位

```c

typedef enum
{
    BSP_DELAY_UNITS_SECONDS      = 1000000, ///< Requested delay amount is in seconds
    BSP_DELAY_UNITS_MILLISECONDS = 1000,    ///< Requested delay amount is in milliseconds
    BSP_DELAY_UNITS_MICROSECONDS = 1        ///< Requested delay amount is in microseconds
} bsp_delay_units_t;
