Please keep things sorted.

Please make the entire comment a C++ one so things look more
intentional.

On/off controls should be standard Switch controls.

I'd expect this to be joined up with whatever caused the register state
to become invalid, this looks like it's inviting bugs.  This also seems
to have only one caller...

The naming seems a bit random here.

This all seems very redundant and like it'll get in the way of grepping
for users.  It would be better to just inline the operation into the clk
API functions.
