我在SDK中看到motor_control例程中，初始化ADC时，它进行寄存器配置，使用的基地址是ADC1的地址，而使用的地址偏移是使用ADC0的偏移，如以下程序
adc_base = CHIPDBBaseAddress(CHIPDB_MOD_ID_ADC1, 0);//0x4834C000 ADC1 Registers
HWREG(adc_base + ADC0_CTRL) = 0 | \
((ADC0_CTRL_HW_PREEMPT_NOPREEMPT << ADC0_CTRL_HW_PREEMPT_SHIFT) | \
((ADC0_CTRL_HW_EVT_MAPPING_HWEVTINPUT << ADC0_CTRL_HW_EVT_MAPPING_SHIFT)) | \
(ADC0_CTRL_TOUCH_SCREEN_EN_DISABLE << ADC0_CTRL_TOUCH_SCREEN_EN_SHIFT) | \
(ADC0_CTRL_STEPCONFIG_WRITEPROTECT_N_NOTPROTECTED << ADC0_CTRL_STEPCONFIG_WRITEPROTECT_N_SHIFT) | \
(ADC0_CTRL_EN_DISABLE << ADC0_CTRL_EN_SHIFT) | \
(ADC0_CTRL_STEP_ID_TAG_WRZERO << ADC0_CTRL_STEP_ID_TAG_SHIFT));
其adc_base是 ADC1 寄存器地址，为什么偏移用 ADC0_CTRL？
