5.2 Peripheral Identification Register (PID)
SRIO Registers
The peripheral identification register (PID) is a constant register that contains the ID and ID revision
number for that peripheral. The PID stores version information used to identify the peripheral. All bits
within this register are read-only (writes have no effect) meaning that the values within this register should
be hard-coded with the appropriate values and must not change from their reset state.
