5.2  Sleep 
As the external controller, as well as the NEOCORTEC Module, is expected to spend a 
lot of time in sleep mode to save power, it is important that wake-up is synchronized, so 
that the modules can communicate with each other. 
The external controller can enter sleep mode when it has finished processing of e.g. 
sensor data on its inputs, or data received from the NEOCORTEC module.  
The NEOCORTEC node controls wake-up exclusively. When the NEOCORTEC node is 
active, the WakeUp signal is active. Likewise, when the NEOCORTEC node is in sleep, 
the WakeUp signal is inactive

The external controller will have to be in active state whenever the NEOCORTEC node is 
in active state. This to ensure that the external controller is ready to receive UART data 
whenever the NEOCORTEC node potentially can send such data. 
For more details, see chapter 6 Serial UART Interface. 
 
6  Serial UART Interface 
The NEOCORTEC NCxxxx module provides two serial communications ports, which are, 
used for each their own individual purpose: 
 
Name 
Desciption 
Application API  Used to interface the Host Controller Application layer 
with the NC2400 Module. Provides functions for sending 
and receiving payload data through the NEOCORTEC 
wireless network 
System API 
Used for configuration and debugging purposes. Will 
typically be connected to a PC when the user either 
configures the module, or during the development 
process to provide trace outputs. 
 
 
The Host Processor can communicate with the NCxxxx module through a standard 
UART serial interface (see module data sheet for electrical details and Pin locations).
