ATmega128RFA1
Table 9-13. Interrupt Handling in Extended Operating Mode
RX_AACK
For RX_AACK it is recommended to enable the TRX24_RX_END interrupt. This
interrupt is issued only if a frame passes the frame filtering (see section
Filtering" on
(see section
optional.
On reception of a valid PHR a TRX24_RX_START interrupt is issued. The TRX24_AMI
interrupt indicates an address match (see filter rules in section
page 54). The completion of a frame reception with a valid FCS is indicated by the
TRX24_RX_END interrupt.
Thus it can happen that a TRX24_RX_START and/or a TRX24_AMI interrupt are
issued, but no TRX24_RX_END interrupt.
The end of an acknowledgment transmission is confirmed by a TRX24_TX_END
interrupt.
TX_ARET
In TX_ARET interrupt TRX24_TX_END is only issued after completing the entire
TX_ARET transaction.
Acknowledgement frames do not issue a TRX24_RX_START, TRX24_AMI or a
TRX24_RX_END interrupt.
All other interrupts as described in section
