8. CP2120 Revision Number

The CP2120 revision number can be retrieved by first sending the Revision Number command byte of 0x40 and

then transmitting one “don’t care” transitional byte. The CP2120 then transmits the two-byte revision number, most

significant byte first, in BCD format. For example, a transmitted byte sequence of “0x01 0x44” would indicate that

the CP2120’s revision number is equal to 1.44.
