If this is a binary output pin, I suspect that I suspect that what you call "off" is actually implemeted as in this figure: http://upload.wikimedia.org/wikipedia/commons/c/c0/Tristate_buffer.svg In which case: PIN_CONFIG_DRIVE_PUSH_PULL PIN_CONFIG_DRIVE_OFF or PIN_CONFIG_BIAS_HIGH_IMPEDANCE Is a config pair which most often correspond to exactly what you're doing here, albeit with a different terminology. However, if it is an *analog* pin.... Then it's something else.
