I have a piezo transducer hooked up to 2 of my attiny85 pins, and I'm driving it via software in AC mode @4khz using a timer and interrupt.
Here is the date sheet of attiny85:

I would like to switch this over to a hardware solution (no interrupt) using OC1B/!OC1B (PB4,PB3), but I'm not sure if it does what I think it does (inverts, OC1B/pb4 = !OC1B/pb3).
Can someone supply pointers or an example that uses OC1B/!OC1B, or how I configure it for inverted output @4khz?
