12.2 INSTRUCTION GROUPS
The ST7 family devices use an Instruction Set
consisting of 63 instructions. The instructions may
Using a prebyte
The instructions are described with 1 to 4 bytes.
In order to extend the number of available op-
codes for an 8-bit CPU (256 opcodes), three differ-
ent prebyte opcodes are defined. These prebytes
modify the meaning of the instruction they pre-
cede.
The whole instruction becomes:
These prebytes enable instruction in Y as well as
indirect addressing modes to be implemented.
They precede the opcode of the instruction in X or
the instruction using direct addressing mode. The
prebytes are:

be subdivided into 13 main groups as illustrated in
the following table:
12.2.1 Illegal Opcode Reset
In order to provide enhanced robustness to the de-
vice against unexpected behavior, a system of ille-
gal opcode detection is implemented. If a code to
be executed does not correspond to any opcode
or prebyte value, a reset is generated. This, com-
bined with the Watchdog, allows the detection and
recovery from an unexpected fault or interference.
Note: A valid prebyte associated with a valid op-
code forming an unauthorized combination does
not generate a reset.
