8.20 Identification

Revision and Device Identification

The hardware revision and device identification values are stored in the memory-mapped FACTORY region,

refer to Device Factory Constants section, which provides read-only data describing the capabilities of a device

as well as any factory-provided trim information for use by application software. Refer to Factory Constants

chapter of the MSPM33C3x 160-MHz Microcontrollers Technical Reference Manual for more information.

The device revision and identification information are also included as part of the top-side marking on the device

package. The device-specific errata sheet describes these markings (see Section 10.4)
