[−][src]Module rp2040::xosc
Controls the crystal oscillator
Modules
| count | A down counter running at the xosc frequency which counts to zero and stops.\n To start the counter write a non-zero value.\n Can be used for short software pauses when setting up time sensitive hardware. |
| ctrl | Crystal Oscillator Control |
| dormant | Crystal Oscillator pause control\n This is used to save power by pausing the XOSC\n On power-up this field is initialised to WAKE\n An invalid write will also select WAKE\n WARNING: stop the PLLs before selecting dormant mode\n WARNING: setup the irq before selecting dormant mode |
| startup | Controls the startup delay |
| status | Crystal Oscillator Status |
