CDSTPNSIF — Coldstart Path Noise Interrupt Flag
This signal is set if the CC has entered startup via the coldstart noise path. This indicates that the CC tried
to start the network. If enabled, an interrupt remains pending while this flag is set.
1 – The startup has been entered via the coldstart noise path.
0 – The startup has not been entered via the coldstart noise path.
CDSTPNIF — Coldstart Path Normal Interrupt Flag
This signal is set if the CC has entered the startup via the normal coldstart path. This indicates that the CC
tried to start the network. If enabled, an interrupt is pending while this flag is set.
1 – Startup has been entered via the normal coldstart path.
0 – Startup has not been entered via the normal coldstart path.

Reset
Each of these registers holds the status of the slot specified in the corresponding slot status selection
register SSSnR for both channel A and channel B. The suffices “_A” and “_B” indicate whether the slot
status is valid for channel A or channel B, respectively. For a detailed description of the slot status flags,
refer to
The controller provides a pair of slot status registers for each monitored slot with the first register being
assigned to even communication cycles, and the second to odd communication cycles, as shown in
Table
The controller clears the slot status registers SSnR (see
