for my target chip, I need 4 IO lines (TX, RX, RST and bootloader_enable).
I looked into the ChipWhisperer capture v2 schematics and found that all 4 IO lines go through a bi-directional level shifter directly to the target.
However, in the ChipWhisperer capture software the only function IO4 pin can have is “HighZ”.
Is there a specific reason why the IO4 Pin can not be used ?
In my application, I need to toggle both the RST as well as the bootloader_enable line in a specific pattern.
