| 63 | description: | |
| 64 | value of reg 0x58, Defines the interrupt source. |
| 65 | Bit(2) 1 means button press triggers irq, 0 means not. |
| 66 | Bit(3) 1 means PIN9 is the irq source for jack detection. When set to 0, |
| 67 | bias change on PIN9 do not triggers irq. |
| 68 | Bit(4) 1 means PIN27 is the irq source for jack detection. |
| 69 | Bit(5) 1 means PIN9 is the irq source after MIC detect. |
| 70 | Bit(6) 1 means PIN27 is the irq source after MIC detect. |

| 77 | description: | |
| 78 | value of reg 0x59, Defines the interrupt output behavior. |
| 79 | Bit(0-3) 0 means irq pulse equals 512*internal clock |
| 80 | 1 means irq pulse equals 1024*internal clock |
| 81 | 2 means ... |
| 82 | 7 means irq pulse equals 65536*internal clock |
| 83 | 8 means irq mutes PA |
| 84 | 9 means irq mutes PA and DAC output |
| 85 | Bit(4) 1 means we invert the interrupt output. |
| 86 | Bit(6) 1 means the chip do not detect jack type after button released. |
| 87 | 0 means the chip detect jack type again after button released. |
