The I/O Type in Table 14-1 of TN1141 is for all the sysCONFIG pins during configuration. For the dual-purpose sysCONFIG pins, when they are used as general purpose I/Os after configuration, they can use any I/O type such as input, output and bi-directional. For example, the INITN pin is bi-directional open drain in the configuration mode. But it can be any I/O type as a general purpose I/O pin when the CFG0 pin is high. Please refer to Section Configuration Pins in TN1141 for the details.
