IRQ Name
IRQ_7 (BAT_LOW)
IRQ_6 (TRX_UR)
IRQ_5 (AMI)
IRQ_4 (CCA_ED_DONE)
IRQ_3 (TRX_END)
IRQ_2 (RX_START)
IRQ_1 (PLL_UNLOCK)
IRQ_0 (PLL_LOCK)
Description
Indicates a supply voltage below the programmed threshold
Indicates a Frame Buffer access violation
Indicates address matching
Multi-functional interrupt:
1. AWAKE_END:
2. CCA_ED_DONE:
RX: Indicates the completion of a frame reception
TX: Indicates the completion of a frame transmission
Indicates the start of a PSDU reception; the TRX state changes to BUSY_RX;
the PHR is valid to be read from Frame Buffer.
Indicates PLL unlock; if the radio transceiver is in BUSY_TX / BUSY_TX_ARET state,
the PA is turned off immediately.
Indicates PLL lock

The AT86RF212 supports 8 interrupt requests as listed in Table 4-15. Each interrupt is
enabled by setting the corresponding bit in the interrupt mask register 0x0E
(IRQ_MASK). Internally, each pending interrupt is stored in a separate bit of the
interrupt status register. All interrupt events are OR-combined to a single external
interrupt signal (IRQ, pin 24). If an interrupt is issued (pin IRQ = H), the microcontroller
shall read the interrupt status register 0x0F (IRQ_STATUS) to determine the source of
the interrupt. A read access to this register clears the interrupt status register and thus
the IRQ pin, too.
Interrupts are not cleared automatically when the event that caused them vanishes.
Exceptions
occurrence of one clears the other.
The supported interrupts for the Basic Operating Mode are summarized in Table 4-15.
