Table 23-150. Interrupt, Counter, and Result Field for Received Packets
Condition
Packet could not be stored due to lack of buffer space
For both types of commands, the packet length may be configured as unlimited or unknown at the start of
packet reception, by setting maxPktLen to 0. This mode can only be used with partial-read RX buffers. If
the length is later determined, it can be set by the immediate or direct command CMD_PROP_SET_LEN,
where the number of bytes between the header (if any) and the CRC is given. In addition to setting the
length this way, packet reception may be stopped in the following ways (CRC check is not performed in
the following cases):
• If CMD_PROP_SET_LEN is called with a smaller number of bytes than already received
• If CMD_PROP_RESTART_RX is given
• If no more RX buffer is available
• If the end trigger occurs and pktConf.endType is 1
• If the command is aborted with CMD_ABORT
For ignored packets and packets with CRC error, automatic flush of the receive buffer can be configured.
In this case, packets are removed from the receive buffer after they have been received, so the next
packet overwrites it and the counters are not updated to reflect the packet received.
NOTE: Automatic flush is not supported for partial-read RX entries. Packets with CRC error (that is,
for which the RX_NOK interrupt is raised) are automatically flushed if
RXConf.bAutoFlushCrcErr is 1.
Ignored packets (that is, for which the RX_IGNORED interrupt is raised) are automatically flushed if
RXConf.bAutoFlushIgnored is 1. After a packet has been received, the next action depends on
pktConf.bRepeat. If this is 0, the command ends. Otherwise, it goes back into RX, unless another criterion
exists that leads to the command to end. When the command ends, the frequency synthesizer is turned
off if pktConf.bFsOff is 1. If pktConf.bFsOff is 0, the synthesizer keeps running, so that the command must
either be followed by an RX or TX command (which operate on the same frequency) or a CMD_FS_OFF
command to turn off the synthesizer.
The end statuses for CMD_PROP_RX and CMD_PROP_RX_ADV are listed in
decides the next operation, see
Table 23-151. End of Radio CMD_PROP_RX and CMD_PROP_RX_ADV Commands
