5.10 Signal  flow 

The signal lines from the I/O connectors and the CC2430 run via 0

Ω

 resistors to the various 

peripherals on the CC2430DB. The peripherals can be disconnected from the CC2430 signal 
pins by removing the 0

Ω

 resistors. Please refer to Table 6 for a list of what resistors 

correspond to which signals.
