IRQ_STATUS
IRQ_STATUS
This register contains the status of the pending interrupt requests. An interrupt is
pending if the associated bit has a value of one. Such a pending interrupts can be
manually cleared by writing a 1 to that register bit. Interrupts are automatically cleared
when the corresponding interrupt service routine is being executed.
• Bit 7 – AWAKE - Awake Interrupt Status
• Bit 6 – TX_END - TX_END Interrupt Status
• Bit 5 – AMI - Address Match Interrupt Status
• Bit 4 – CCA_ED_DONE - End of ED Measurement Interrupt Status
• Bit 3 – RX_END - RX_END Interrupt Status
• Bit 2 – RX_START - RX_START Interrupt Status
• Bit 1 – PLL_UNLOCK - PLL Unlock Interrupt Status
• Bit 0 – PLL_LOCK - PLL Lock Interrupt Status
