8.7. General Purpose I/O
The general-purpose I/O pads can be configured to act in three different ways:
• Input
• Output
• Alternate function (internally controlled)
Input pads can only be read and report digital values (high or low) present on the pad at the read
time. Output pads can only be written or queried and set the value of the pad output. An
alternate function pad is internally controlled by LE910C1 firmware and acts depending on the
implemented function.
The following GPIOs are always available as a primary function on the LE910C1.
