| 7 | * |
| 8 | * --- Notes from Thomas's original driver --- |
| 9 | * This is the lowlevel driver for the AMD7930 audio chip found on all |
| 10 | * sun4c machines and some sun4m machines. |
| 11 | * |
| 12 | * The amd7930 is actually an ISDN chip which has a very simple |
| 13 | * integrated audio encoder/decoder. When Sun decided on what chip to |
| 14 | * use for audio, they had the brilliant idea of using the amd7930 and |
| 15 | * only connecting the audio encoder/decoder pins. |
| 16 | * |
| 17 | * Thanks to the AMD engineer who was able to get us the AMD79C30 |
| 18 | * databook which has all the programming information and gain tables. |
| 19 | * |
| 20 | * Advanced Micro Devices' Am79C30A is an ISDN/audio chip used in the |
| 21 | * SparcStation 1+. The chip provides microphone and speaker interfaces |
| 22 | * which provide mono-channel audio at 8K samples per second via either |
| 23 | * 8-bit A-law or 8-bit mu-law encoding. Also, the chip features an |
| 24 | * ISDN BRI Line Interface Unit (LIU), I.430 S/T physical interface, |
| 25 | * which performs basic D channel LAPD processing and provides raw |
| 26 | * B channel data. The digital audio channel, the two ISDN B channels, |
| 27 | * and two 64 Kbps channels to the microprocessor are all interconnected |
| 28 | * via a multiplexer. |
