SN10-1x interfaces to the MCU via a 5-wire SPI interface. In addition to the regular 4-wire interface with CS, CLK, MOSI and MISO pins, ACK pin is also available for the module (slave) to signal the MCU (master) when there is data ready to transfer to the MCU. For the low power mode to work properly without leakage current, it is important all pins on MCU are pulled low and only CS and ACK should be high. Please refer to “SN10-1x Software Development Guide” available on the Innocomm website for detail of the SPI interface and protocol.
