Good that you tried to use bitwise operators, but in this case you have a great enum called PinState that already encodes the two possible states and is easier to read than using bitwise logic. You can use the already existing PinState enum, if it doesn't have a clear value assinged to high and low you can do it like this in the enum definition:

enum class PinState : uint8_t {
    HIGH = 1,
    LOW = 0,
},

As I said in the other comments, I don't know the exact variant name, but you get the idea

LGTM (Looks Good To Me), we'll have to make some small changes in the future to integrate with the latest changes Jorge is working on, but will work for now.
