6. Radio Hardware Interface
The EZRadioPRO devices can be controlled by the host MCU over an SPI bus and six additional signals. The user
has access to the radio's API via the SPI bus.
Figure 5. Connections between the Host MCU and the Radio
The high state of the shutdown (SDN) pin is used to completely disable the radio and put the device into the lowest
power consumption state. The radio has an interrupt output pin (NIRQ) which can be used to promptly notify the
host MCU of multiple events. The NIRQ pin is active low, and goes back to high if the pending interrupt flag is
cleared by reading the appropriate interrupt pending registers.
