General-Purpose Input/Outputs (GPIOs)
Register 29: GPIO PrimeCell Identification 2 (GPIOPCellID2), offset 0xFF8
The GPIOPCellID0, GPIOPCellID1, GPIOPCellID2, and GPIOPCellID3 registers are four 8-bit
wide registers, that can conceptually be treated as one 32-bit register. The register is used as a
standard cross-peripheral identification system.
