Functions#

void
halInit(void)

Initializes microcontroller-specific peripherals.

void
halReboot(void)

Restarts the microcontroller and therefore everything else.

void
halPowerUp(void)

Powers up microcontroller peripherals and board peripherals.

void
halPowerDown(void)

Powers down microcontroller peripherals and board peripherals.

void
halResume(void)

Resumes microcontroller peripherals and board peripherals.

void
halSuspend(void)

Suspends microcontroller peripherals and board peripherals.

void
halInternalEnableWatchDog(void)

Enables the watchdog timer.

void
halInternalDisableWatchDog(uint8_t magicKey)

Disables the watchdog timer.

bool
halInternalWatchDogEnabled(void)

Determines whether the watchdog has been enabled or disabled.

void
halSleep(SleepModes sleepMode)

Puts the microcontroller to sleep in a specified mode.

void
halSleepPreserveInts(SleepModes sleepMode)

Same as halSleep() except it preserves the current interrupt state rather than always enabling interrupts prior to returning.

void
halCommonDelayMicroseconds(uint16_t us)

Blocks the current thread of execution for the specified amount of time, in microseconds.

void
halCommonDisableVreg1v8(void)

Disable the 1.8V regulator. This function is to be used when the 1.8V supply is provided externally. Disabling the regulator saves current consumption. Disabling the regulator will cause ADC readings of external signals to be wrong. These exteranl signals include analog sources ADC0 thru ADC5 and VDD_PADS/4.

void
halCommonEnableVreg1v8(void)

Enable the 1.8V regulator. Normally the 1.8V regulator is enabled out of reset. This function is only needed if the 1.8V regulator has been disabled and ADC conversions on external signals are needed. These exteranl signals include analog sources ADC0 thru ADC5 and VDD_PADS/4. The state of 1v8 survives deep sleep.

void
halBeforeEM4(uint32_t duration, RTCCRamData input)

Enumeration Documentation#

SleepModes#

SleepModes

Enumerations for the possible microcontroller sleep modes.

  • SLEEPMODE_RUNNING Everything is active and running. In practice this mode is not used, but it is defined for completeness of information.

  • SLEEPMODE_IDLE Only the CPU is idled. The rest of the chip continues running normally. The chip will wake from any interrupt.

  • SLEEPMODE_WAKETIMER The sleep timer clock sources remain running. The RC is always running and the 32kHz XTAL depends on the board header. Wakeup is possible from both GPIO and the sleep timer. System time is maintained. The sleep timer is assumed to be configured properly for wake events.

  • SLEEPMODE_MAINTAINTIMER The sleep timer clock sources remain running. The RC is always running and the 32kHz XTAL depends on the board header. Wakeup is possible from only GPIO. System time is maintained. NOTE: This mode is not available on EM2XX chips.

  • SLEEPMODE_NOTIMER The sleep timer clock sources (both RC and XTAL) are turned off. Wakeup is possible from only GPIO. System time is lost.

  • SLEEPMODE_HIBERNATE This maps to EM4 Hibernate on the EFM32/EFR32 devices. RAM is not retained in SLEEPMODE_HIBERNATE so waking up from this sleepmode will behave like a reset. NOTE: This mode is only available on EFM32/EFR32

halCommonDelayMicroseconds#

void halCommonDelayMicroseconds (uint16_t us)

Blocks the current thread of execution for the specified amount of time, in microseconds.

Parameters
N/Aus

The specified time, in microseconds. Values should be between 1 and 65535 microseconds.

The function is implemented with cycle-counted busy loops and is intended to create the short delays required when interfacing with hardware peripherals.

The accuracy of the timing provided by this function is not specified, but a general rule is that when running off of a crystal oscillator it will be within 10us. If the micro is running off of another type of oscillator (e.g. RC) the timing accuracy will potentially be much worse.
