Expand description
PMC - Power Management Controller
The PMC controls the Low Voltage Detect and the ADC bandgap voltage reference functions.
TODO: write an example
Low Voltage Detect
Low Voltage Detect Reset
This feature, when enabled can trigger a reset when the MCU’s input voltage drops below a selectable voltage threshold. This functionality can be active in both running and stop modes (default) or in running mode only.
Low Voltage Warning
This feature sets a warning flag bit and optional triggers an interrupt when the warning voltage threshold has been crossed. This threshold is user-selectable with 8 options grouped into sets of 4 which depend on which low voltage detect reset threshold is chosen.
Bandgap Voltage Reference
The PMC contains a field that enables the internal buffer for the bandgap voltage reference used by the ADC adn ACMP peripherals. This is impelemented in those areas.
Structs
| Disabled | The function is Disabled. |
| DontCare | The current state doesn’t matter for reasons. |
| Enabled | The function is Enabled. |
| Flag | The low voltage warning is a flag only. |
| Interrupt | The low voltage warning triggers an interrupt (and a flag). |
| LVReset | Interface that controls when the Low Voltage Detection is active |
| LVWarn | Interface for the low voltage warning / interrupt |
| Pmc | Datastructure for PMC interface |
| RunAndStop | The low voltage detection (for reset) is active while the MCU is in run and stop modes. |
| RunOnly | The low voltage detection (for reset) is active only while MCU is in a run mode |
| _2v6 | V_LVDL threshold = 2.61V typ. for all KEA parts |
| _4v3 | V_LVDH threshold = 4.3V typ. for all KEA parts. |
Enums
| Error | Error Enumeration |
| LvwHigh | Low Voltage Warning Threshold, High range (set by V_LVDx). |
| LvwLow | Low Voltage Warning Threshold, Low range (set by V_LVDx). |
