The general-purpose interface combines eight general-purpose input/output (GPIO) banks.
Each GPIO module provides 32 dedicated general-purpose pins with input and output capabilities; thus, the general-purpose interface supports up to 247 pins.
These pins can be configured for the following applications:
The general-purpose input/output i (i = 1 to 8) bank is also referred to as GPIOi.
