Preliminary
Register 26: GPIO Peripheral Identification 3 (GPIOPeriphID3), offset 0xFEC
The GPIOPeriphID0, GPIOPeriphID1, GPIOPeriphID2, and GPIOPeriphID3 registers can
conceptually be treated as one 32-bit register; each register contains eight bits of the 32-bit
register, used by software to identify the peripheral.
Bit/Field Name Type Reset Description
31:8 reserved RO 0 Reserved bits return an indeterminate value, and should never
be changed.
7:0 PID3 RO 0x01 GPIO Periphe ral ID Register[31:24]
Can be used by software to identify the presence of this
peripheral.
