4.0 STANDARD VERSION MEMORY MAP
The memory spase, as seen by ST7 is defined in table 4; please take note that there are registers which
are used for less than 8 bit or, on the other side, when read only certan bit contain useful information. Re-
ferr to appendix a to have a complete list of register structure.
