microcontroller - GPIO programming of MSP430? -

-

i going through datasheet of msp430 series.

my doubt :

there register enabling or disabling pull , pull down registers.(pxren)

my question , if configure pin input , disable internal pull , pull down registers using register pxren , state of pin @ time , tri stated?

yes. when configure pin gpio input high-z, i.e. tri stated. that's perfect input pin, external hardware define level.

when enable rxen resistor pull or down. depends on value in out register.
