msp430f149比较器,设置为:使用外部参考源P2CA0 = 0 ,P2CA1=0, CAPD |=CAPD3+CAPD4, CA1端口悬空 时,为何有2V电压?

Other Parts Discussed in Thread: MSP430F149

msp430f149比较器,设置为:使用外部参考源P2CA0 = 0  ,P2CA1=0, CAPD |=CAPD3+CAPD4,    CA1端口悬空 时,为何有2V电压;在CA1端口接上一个10K电阻,电压为1.9V,  是不是msp430f149比较器的CA1端  的漏电流为190uA    ?

弄了 一周了,还是这样,但比较器可以正常工作,这是什么原因啊?
