手册上看REF到有写:
The reference module (REF) is responsible for generation of all critical reference voltages that can be
used by various analog peripherals in a given device. These include, but are not necessarily limited to, the
ADC10_A, ADC12_A, DAC12_A, LCD_B, and COMP_B modules dependent upon the particular device.
其中没提到SD24,是不是SD24的内部基准电压只能用1.2V,如果需要更高的基准电压就要通过外部基准来实现?
我自己试过设置REFCTL0中的REFVSEL和REFON置位,但貌似没有起作用。
如果能够调内部基准的话,请高手告知需要调哪几个寄存器的值,谢谢!
