EFR32xG2x-specific interrupt sources.

Below are the interrupt handlers implemented within the RAIL library for EFR32 Series 2. See EFR32 for more details about interrupt initialization and priorities. For more information about the interrupt vectors and where they are on your specific chip, see the startup_efr32xg2xx.c file for your chip. These can be found under the Device/SiliconLabs folder in your release.

FRC_PRI_IRQHandler#

void EFR32xG2x_Interrupts::FRC_PRI_IRQHandler (void)

RAIL interrupt handler for the high-priority FRC_PRI interrupt source.

Parameters
N/A

This source handles interrupts from the FRC High Priority. It is not used at this time.

Note

  • The interrupt vector should still point to the RAIL interrupt handler for compatibility with future RAIL releases.

Definition at line 163 of file chip/efr32/efr32xg2x/rail_efr32xg2x_interrupts.h

BUFC_IRQHandler#

void EFR32xG2x_Interrupts::BUFC_IRQHandler (void)

RAIL interrupt handler for the BUFC interrupt source.

Parameters
N/A

This source handles interrupts generated from the radio buffer controller. The following events are currently in use:

  • RX Buffer Threshold

  • RX Buffer Underflow

    • This event cannot be disabled and indicates that too much data was read from the RX buffer. It should not occur in normal operation as all receive APIs protect against it.

  • RX Buffer Corruption

    • This event cannot be disabled and indicates the pointers in the RX buffer have become corrupt. This event should not occur in normal operation.

  • TX Buffer Threshold

  • TX Buffer Overflow

    • This event cannot be disabled and indicates too much data was placed into the TX buffer. This event should not occur in normal operation as all transmit APIs protect against it.

  • TX Buffer Underflow

    • This event cannot be disabled and occurs when the transmit FIFO runs out of bytes before the end of the packet. This event will always perform any necessary cleanup and will call the eventsCallback if RAIL_EVENT_TX_UNDERFLOW is enabled.

  • TX Buffer Corruption

    • This event cannot be disabled and indicates the pointers in the TX buffer have become corrupt. This event should not occur in normal operation.

  • RX Entry Buffer Threshold

  • RX Entry Buffer Underflow

    • This event cannot be disabled and indicates that too much data was read from the RX entry buffer. This event should not occur in normal operation.

  • RX Entry Buffer Overflow

    • This event cannot be disabled and will fire one time if the RX entry buffer overflows. It will cause the RAIL_EVENT_RX_FIFO_OVERFLOW event to happen later after all valid entries are processed in the RX entry buffer.

  • RX Entry Buffer Underflow

    • This event cannot be disabled and indicates that too much data was read from the RX entry buffer. This event should not occur in normal operation.

  • RX Entry Buffer Corruption

    • This event cannot be disabled and indicates the pointers in the RX entry buffer have become corrupt. This event should not occur in normal operation.

Parameters
N/A

This source handles interrupts generated from the RAIL timebase (PROTIMER). The following events are currently in use:

  • Scheduled TX/RX

    • This event cannot be disabled and occurs when a scheduled transmit or receive begins.

  • RX scheduled window end timeout

    • This event cannot be disabled and occurs when the scheduled receive window ends and the radio exits receive. This event will call the eventsCallback if RAIL_EVENT_RX_SCHEDULED_RX_END is enabled.

  • Transmit with CCA Failed

    • This event cannot be disabled and occurs when CCA indicates the channel is busy. This event will call the eventsCallback if RAIL_EVENT_TX_CHANNEL_BUSY is enabled.

  • Transmit with CCA Success

    • This event cannot be disabled and occurs when CCA indicates the channel is clear and the packet will be transmitted. This event will call the eventsCallback if RAIL_EVENT_TX_CHANNEL_CLEAR is enabled.

  • Starting a CCA check

  • CCA Retry

  • RAIL Timer

    • This event is enabled by RAIL_SetTimer() and will call the provided callback when the timer expires.

Parameters
N/A

This source handles interrupts generated from the RF Sense module. This source is not available on all EFR32 Series 2 devices. The following events are currently in use:

This event will possibly generate a callback provided to RAIL_StartRfSense whenever the RFSENSE block detects RF energy.
