Which among the below mentioned statements are precisely related to quasi-bidirectional port? A. Fixed high pull-up resistors are internally connected B. Configuration in the form of input pulls the port at higher position whereas they get pulled lower when configured as a source current C. It is possible to drive the pin as output at any duration when FET gets turned OFF for an input function D. Upper pull-up FET is always OFF with the provision of ‘open-drain’ output pin for normal operation of port
