The AWR1443 device communicates with the host radar processor over the following main interfaces:
- Reference Clock – Reference clock available for host processor after device wakeup
- Control – 4-port standard SPI (peripheral) for
host control . All radio control commands (and
response) flow through this interface.
- Reset – Active-low reset for device wakeup from host
- Out-of-band interrupt
- Error – Used for notifying the host in case the radio controller detects a fault
