The conditions for giving each status are listed for each operation. Some of the error causes listed in
Table 23-110 are not repeated in these lists. In some cases, general error causes may occur. In all of
these cases, the result of the operation is ABORT.
23.6.4.1 Link Layer Connection
At the start of a slave or master operation, the radio CPU waits for the start trigger, then program the
frequency based on the channel parameter of the command structure. The channel parameter is not
allowed to be 37, 38, or 39, as these are advertising channels. The radio CPU sets up the access address
defined in pParams ->accessAddress, and uses the CRC initialization value defined in pParams ->crcInit.
The whitener is set up as defined in the whitening parameter. The radio CPU then configures the receiver
or transmitter. The operation continues with reception and transmission in turn, until it is ended by one of
the end of command criteria.
When the demodulator obtains sync on a message, the message is received into the first available RX
buffer that can fit the packet. The flags bCrcErr and bIgnore are set according to
on the CRC result, and whether the SN field of the header was the same as the SN field of the last
successfully received packet. A received packet that has a payload length of 0 is viewed as an empty
packet. This means that if pParams ->rxConfig.bAutoflushEmpty is 1 and bCrcErr and bIgnore are both 0,
the packet is removed from the RX buffer.
