5.2.2.1. Direct Mode RX
In RX direct mode, the RX Data and RX Clock can be programmed for direct (real-time) output to GPIO pins. The
microcontroller may then process the RX data without using the FIFO or packet handler functions of the RFIC.
The GPIOs of the radio used for the RX_DATA and RX_DATA_CLK output can be changed without generating a
new configuration file again. In the
radio_config.h
file, insert or modify the definition for the given GPIO as shown
below.
Replace the value with the corresponding property value. For the GPIO configuration options and values, refer to
the API documentation.

5.2.2.2. Direct Mode TX
The radio can be used in direct transmission mode. In this mode the data to be sent should be fed externally to the
radio chip using one of its GPIOs. The GPIO used to input TX_DATA is configured by the EZConfig array, which
means that a new EZConfig array will be generated each time this pin is changed. Optionally, the TX_DATA_CLK
output can be changed via replacing the desired GPIO define value with the corresponding TX_DATA_CLK value.
This modification doesn’t require new EZConfig Array generation. For the GPIO configuration options and values,
refer to the API documentation.
