CommDIO I2C (when used as
input)
CommDIO (UART when used as
a digital input channel)
CommDIO SPI (when used as a
digital input channel)
Note that CommDIO input signals are floating in support of high-bandwidth communications. In certain
applications, external pull-up resistors may be used but are not typically required.
