+description: |
+ The general-purpose interface combines general-purpose input/output (GPIO) banks.
+ Each GPIO banks provides up to 32 dedicated general-purpose pins with input
+ and output capabilities; interrupt generation in active mode and wake-up
+ request generation in idle mode upon the detection of external events.
