SLG46826V IO0 (Pin2): can not be set to Digital input/output in GreenPAK designer

Question

The available options for IO0 are: 
 
 Pin not used 
 digital input 
 digital output 
 
 However the datasheet does not document this restriction and mentions this is GPIO: so why is Digital input/output not an available option in GreenPAK designer V6.36?

However both IO can be configured as Open-Drain (our usage) so I would suspect that the input could still be read in the matrix and give a valid result even for pins without OE 
 No, the issue is that if you use OE to set the pin as output, you also disable the input because of this: 
 
 This is a weird quirk of GreenPAKs, I don't get why you would want to block the input function if a pin is set as output, but it is the way they are. If a pin is set to output, its input returns a 0.

Hi, 
 First of all please update the designer software to latest version. 
 The PINs has OE terminal which indicates it can be set as Digital input/output. 
 Since the OE&rsquo;s state decides the PIN will work as Input mode or Output mode.

Thanks
