Use it to reset controller and to select data rate. According to Intel 80277AA datasheet, software reset behaves the same as DOR reset except that it is self clearing. National Semiconductor PC8477B datasheet says the same. As a side effect, we no longer use Configuration Control Register (CCR) at 0x3f7 for these controllers, which is often missing in modern hardware. |
