Steve:

You have set, on, & off, should you also have clr?

There's never enough time to do it right, but always enough time to do it over...

Hmm, … but you could just do `$data = 0;` or did I understand you wrong?	[reply] [d/l]

Do you mean `clr` on a single bit? ie. do you mean 'unset' (or zero) it?, or do you mean the entire byte? I can definitely add that for completeness, but as soonix stated, `$data = 0;` will do it too.	[reply] [d/l] [select]

My thought was that James wanted _clr is to _set as _off is to _on... But that's not really necessary, since all you need to do is `_set($data, $lsb, $bits, 0)`.	[reply] [d/l]

Bingo! While not necessary, it seems that clr would complete the API. As an old assembly coder, I think in terms of setting, clearing and flipping/toggling bits. As a minor nit pick... Setting a bit "on" or "off" doesn't tell you if the hardware is turning a device "on" or "off". Depends on how the designer set up the hardware. Active high? Active low? Could be either.
