General Purpose I/O

The general-purpose I/O pads can be configured to act in three different ways:

• Input

• Output

• Alternative function (internally controlled)

Input pads can only be read, reporting digital values (high / low) present on the pad at the

reading time. Output pads can only be written or queried and set values on the pad

output. Alternative function pads can be internally controlled by LE910Cx firmware and act

according to the implementation.

The following GPIOs are always available as a primary function on the LE910Cx.
