Awake Interrupt

Use Cases:

• PHY_EVENT_ED
• PHY_EVENT_CCA

PHY_EVENT_AWAKE_END

When leaving the state SLEEP, as described in PHY_STATE_SLEEP__TRX_OFF, the TRX_IRQ_AWAKE_END indicates that the radio transceiver has entered the state TRX_OFF.

This interrupt is also issued in the use cases Reset and Power-On Reset.

Note:

IRQ_4 (TRX_IRQ_CCA_ED_DONE) is a multi-functional interrupt. Depending on the transceiver state it either denotes the interrupt TRX_IRQ_AWAKE_END or the interrupt TRX_IRQ_CCA_ED_DONE.

Code example

    /* AT86RF231::SLEEP */
    trx_pinset_slptr(0);
    delay(tTR2);
    /* AT86RF231::TRX_OFF && MCU::ISR */
    cause = trx_reg_read(RG_IRQ_STATUS);
    /* MCU::ISR_AWAKEEND */
