Force UART operation
Condition
You configure a device with only the SPI enabled and no SPI master is available to access the SPI slave
port
Solution
Use the following steps to recover the device to UART operation:
1. Hold the DIN/CONFIG low at reset time.
2. DIN/CONFIG forces a default configuration on the UART at 9600 baud and brings up the device
in Command Mode on the UART port.
You can send the appropriate commands to the device to configure it for UART operation.
3. If you write these parameters to the device, the module comes up with the UART enabled on
the next reset.
