GPIOWKEN=dis, HIRCPD=active, MODE=active
Power Management.
| MODE | Operating Mode. This two bit field selects the current operating mode for the device. Note that code execution only occurs during ACTIVE mode. 0 (active): Active Mode. 2 (deepsleep): DeepSleep Mode. 3 (shutdown): Shutdown Mode. 4 (backup): Backup Mode. |
| GPIOWKEN | GPIO Wake Up Enable. This bit enables all GPIO pins as potential wakeup sources. Any GPIO configured for wakeup is capable of causing an exit from IDLE or STANDBY modes when this bit is set. 0 (dis): Wake Up Disable. 1 (en): Wake Up Enable. |
| RTCWKEN | RTC Alarm Wake Up Enable. This bit enables RTC alarm as wakeup source. If enabled, the desired RTC alarm must be configured via the RTC control registers. |
| USBWKEN | USB Wake Up Enable. This bit enables USB activity as wakeup source. |
| WUTWKEN | WUT Wake Up Enable. This bit enables WUT IRQ as wakeup source. |
| compwken | COMPARATOR Input Wake Up Enable. This bit enables COMP IRQ activity as wakeup source. |
| HIRCPD | HIRC Power Down. This bit selects HIRC power state in DEEPSLEEP mode. 0 (active): Mode is Active. 1 (deepsleep): Powered down in DEEPSLEEP. |
| HIRC96MPD | 96MHz power down. This bit selects 96MHz HIRC power state in DEEPSLEEP mode. |
| HIRC8MPD | 8MHz power down. This bit selects 8MHz HIRC power state in DEEPSLEEP mode. |
| XTALPB | 32MHz Bluetooth Oscillator Bypass. |
