Device Connections
Digital Pins
Only a small number of digital pins are dedicated to a single function; whenever possible, the digital pins have a
default function, and also can be reprogrammed to cover alternative functions for various applications.
The fixed-function pins are Reset and the SPI_Select pin, which are HW control pins. Depending on the state of
SPI_Select, the two control-bus pins SCL/SS and SDA/MOSI are configured for either I
2
C or SPI protocol.
Other digital IO pins can be configured for various functions via register control. An overview of available
functionality is given in Multifunction Pins.
