| 78 | Notes: |
| 79 | * group "mpp_audio1" allows the following functions and gpio pins: |
| 80 | - gpio : gpio on pins 52-57 |
| 81 | - i2s1/spdifo : audio1 i2s on pins 52-55 and spdifo on 57, no gpios |
| 82 | - i2s1 : audio1 i2s on pins 52-55, gpio on pins 56,57 |
| 83 | - spdifo : spdifo on pin 57, gpio on pins 52-55 |
| 84 | - twsi : twsi on pins 56,57, gpio on pins 52-55 |
| 85 | - ssp/spdifo : ssp on pins 52-55, spdifo on pin 57, no gpios |
| 86 | - ssp : ssp on pins 52-55, gpio on pins 56,57 |
| 87 | - ssp/twsi : ssp on pins 52-55, twsi on pins 56,57, no gpios |
| 88 | * group "audio0" internally muxes i2s0 or ac97 controller to the dedicated |
| 89 | audio0 pins. |
| 90 | * group "twsi" internally muxes twsi controller to the dedicated or option pins. |
