71M652X Software User’s Guide
A map of the Special Function Registers is shown in Table 6-4. Only a few addresses are occupied, the others are not
implemented. SFRs specific to the 652X are shown in bold print (see 71M652X data sheet for descriptions of these
registers). 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.
