Which WP7702 ULPM wake up sources are supported by Octave 3.2.1 - FX30S via the power connector?

Looking at the documentation I think that only timer is available.

### FX30S Power and IO Connections

| Name | WP INPUT / ADC |
| --- | --- |
| IO1 (Pin 4) | GPIO2 |
| IO2 (Pin 5) | GPIO21 |
| IO2 (Pin 5) | ADC 1 |
| IO3 (Pin 6 ) | GPIO22 |

### Octave ULPM wakeup sources

From the current web docs - [This link that is sure to be broken before long](https://docs.octave.dev/docs/controlling-ultra-low-power-mode#configuring-how-the-device-wakes-from-ulpm)

Section “Wake from a GPIO”

ID _2_ or _3_ to configure the respective ADC pin.  
ID _36_ or _38_ to specify the respective GPIO to boot.
