The CHIP tag is a 16-bit unsigned integer that denotes the type of chip the firmware is to be installed to. It is one of the few tags that is not read from the fuses, but is instead hardcoded in the bootchain. It is used to prevent incompatible firmwares from being installed; different processors may have their MMIO registers in different locations.

Recovery Mode string
If you connect a device in Recovery Mode to your computer, there is a small section in the device's USB "serial number" that contains the CPID, among other information.
