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:
Load and Transfer
Stack operation
Increment/Decrement
Compare and Tests
Logical operations
Bit Operation
Conditional Bit Test and Branch
Arithmetic operations
Shift and Rotates
Unconditional Jump or Call
Conditional Branch
Interruption management

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.
