7.1 Processor Identification
Two read-only registers are provided to allow software to identify the Rabbit microproces-
sor and recognize the features and capabilities of the chip. Five bits in each of these regis-
ters are unique to each version of the chip. One register (GCPU) identifies the CPU, and
the other register (GREV) is reserved for revision identification. The CPU identification
(GCPU) of all revisions of the Rabbit 2000 microprocessor is the same. Rabbit 2000 revi-
sions are differentiated by the value in the GREV register. Refer to Section B.2.2 for more
information.
