| AY-3-8930 |
DIP40 |
* The pulse width can be changed from square to four other duty cycles. * There are three independent envelope generators, one for each channel. * The amplitude control is more accurate (5 bit instead of 4 bit). * The tone period setting is more accurate (16 bit vs 12 bit). * The noise period setting is more accurate (8 bit vs 5 bit). * The noise tone can be changed by applying an AND and OR mask to the output. * The function of the BC2 pin is changed (it is ignored and assumed to be 0 regardless of the pin state). |
