The PrimeCell GPIO offers:
Compliance to the AMBA Specification (Rev 2.0) onwards for easy integration into SoC implementation.
Individually programmable input/output pins, default to input at reset.
Programmable interrupt generation capability, from a transition or a level condition, on any number of pins.
Each of the four GPIO blocks has a connection to the VIC.
Bit masking in both read and write operations through address lines.
Identification registers that uniquely identify the PrimeCell GPIO.
