The following state diagrams and explanations help to illustrate the behavior during Self
Polling Mode. First, there is a wake up search for a wake up pattern according
configuration A on up to three different channels. Then, there is an optional search for a
wake up pattern according configuration B, again including up to 3 channels.
In applications using only a single configuration, settings are always taken from
Configuration A

DCE: Dual Configuration Enable
This Bit is relevant only in Self Polling Mode. It defines whether both
configurations are used.
0: Only Config A is used
1: First Config A is used; then Config B is used
RFPLLACS: Actual Channel
This register is set after a Wake Up found in the Self Polling Mode
00b: No channel was actually found
01b: Channel 1 according to RFPLL1 setting was found
10b: Channel 2 according to RFPLL2 setting was found
11b: Channel 3 according to RFPLL3 setting was found
NOC: Number of channels
Only used in the Self Polling Mode to define how many channels have to be
scanned. In the Slave Mode there is only 1 channel used, whatever here is
configured.
Min: 01b = 1 channel
Max: 11b= 3 channels
