6.11 Point-to-point Auxiliary I/O
The simplest way to route auxiliary I/Os is in a point-to-point network as shown in Figure 24.

Figure 24: Point-to-point routing of auxiliary I/Os
In this scenario, the master has I/O 0 configured as an output, and I/O 1 configured as an input, while the
slave has I/O 0 configured as an input and I/O 1 configured as an output. I/O2 2 through 7 are not used.
The input applied to I/O 0 on the slave will be mirrored on the master, while the input applied to I/O 1 on the
master will be mirrored on the slave. The power-up default for the output I/O on both radios is low.
More information on configuring the I/O can be found in section 5.4 on page 41.
