3.16 DEVELOPMENT / DEBUG ON CHIP
This is the interface with the SX1441 development tool. It includes the DOC_SCK and DOC_SDIO pins. They are
powered by VDDIO_DIG and VSSIO_DIG.
When in normal operation in applications, DOC_SCK and DOC_SDIO should remain unconnected (N.C)
When operated in development / debug mode DOC_SCK and DOC_SDIO, in addition to VDDIO_DIG and
VSSIO_DIG, are connected to the SX1441 development tools through the appropriate interface. For more details,
please contact Semtech technical support.
