I do not understand why the dead-band generator in 28069 is made the way it is.
My particular concern is the A / B swap circuitry (S4 and S5 in 28069) BEFORE the RED and FED generators, why hasn't it been placed AFTER the generators?
The way it is now RED is hard-wired to the A output and FED to the B output.
It is easy to swap A and B in software where the flexibility is excellent, so the hardware is redundant and very much missed after the generators.
My particular problem is that I need to be able to swap between low-side switch idle-looping and high-side switch idle-looping in a power supply, which
would be possible if the A / B switching circuitry had been placed after the generators.
