Only a few addresses are occupied, the others are not implemented. SFRs specific to the 78M6612 are
shown in bold print. Any read access to unimplemented addresses will return undefined data, while any
write access will have no effect. The registers at 0x80, 0x88, 0x90, etc., are bit-addressable, all others
are byte-addressable.
