Interrupt Handling
or TRAC_STATUS = SUCCESS_DATA_PENDING if the frame pending subfield of the received
ACK frame was set to 1.
The interrupt handling in the Extended Operating Mode is similar to the Basic Operating Mode,
refer to
setting the appropriate bit in register 0x0E (IRQ_MASK).
For RX_AACK and TX_ARET the following interrupts inform about the status of a frame recep-
tion and transmission:
Table 7-13.
RX_AACK
For RX_AACK it is recommended to enable IRQ_3 (TRX_END). This interrupt is issued only if a
frame passes the frame filtering, refer to
valid FCS. This is in contrast to Basic Operating Mode, refer to
on page
On reception of a valid PHR an IRQ_2 (RX_START) is issued. IRQ_5 (AMI) indicates address
match, refer to filter rules in
a frame reception with a valid FCS is indicated by interrupt IRQ_3 (TRX_END).
Thus, it can happen that an IRQ_2 (RX_START) and/or IRQ_5 (AMI) are issued, but no IRQ_3
(TRX_END) interrupt.
TX_ARET
In TX_ARET interrupt IRQ_3 (TRX_END) is only issued after completing the entire TX_ARET
transaction.
Acknowledgement frames do not issue IRQ_5 (AMI) or IRQ_3 (TRX_END) interrupts.
All other interrupts as described in
Extended Operating Mode.
