<b>Bi-Phase Outputs </b>
The ability to automatically have one output inversely track another.
This would be very useful for creating bi-phase signals without the use of external logic. The two main things I can think of where this would be useful is for SOUND, allowing the volume of a directly connected Piezo to be increased and for output drives to H-Bridges, but it might have some use for driving bi-colour LED's.
It's also handy when bit-banging bi-phase and an interrupt could occur between the HIGH/LOW or LOW/HIGH pair.
Additional commands for bi-phase operation would be acceptable, but having a 'BIPHASE frompin, topinsmask' per 'frompin' command and the X2's handling all the work automatically when the 'topin' is altered thereafter would be really nice.
<b>Software PWMOUT </b>
Current PWMOUT is not very good for creating variable frequency output, with just 255 steps. Something which allowed finer control / more steps and ran continuously in the background ( barring SLEEP, SERIN etc ) would be nice even if it had fixed 50-50 duty cycle.
