Read-only registers in the system control module provide information about the microcontroller, such as version, part number, pin count, operating temperature range and available peripherals on the device. The Device Identification 0 (see DID0) and Device Identification 1 (see DID1) registers provide details about the device version, package, temperature range, and so on. The Peripheral Present registers starting at system control offset 0x300, such as the Watchdog Timer Peripheral Present (PPWD) register, provide information on how many of each type of module are included on the device. Finally, information about the capabilities of the on-chip peripherals are provided at offset 0xFC0 in the register space of each peripheral in the Peripheral Properties registers, such as the GPTM Peripheral Properties (GPTMPP). In addition, four unique identifier registers, Unique Identifier n (UNIQUEIDn), provide a 128-bit unique identifier for each device that cannot be modified.
