What PSG registers actually trigger the oscillator/envelope generator when
written to?
For example, writing the fine tone does not retrigger the oscillator
(yielding smooth pitch transitions) but writing the coarse tone seems to
restart the wave, with the annoying "pop" (and IMO it's not a matter of too
diferent pitch since I've tested an equivalent transition on an Amiga with
smooth results).

Same goes for envelopes. Which register(s) actually cause the EG to restart?
Has anybody btw used the EG to create triangle and sawtooth tone waveforms
like it was used on some great games & demos on the Atari ST?
Kiss you lot.
