The host interface can be provided through a SPI,
LIN, UART, or CAN-FD interface.
The AWRL1432 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.
- Host Interrupt - an indication that the mmWave
sensor needs host interface
- Error – Used for notifying the host in case the radio controller detects a fault
