Instruction groups
Introduction
The ST7 family devices use an instruction set consisting of 63 instructions. The instructions
may be subdivided into 13 main groups as illustrated in the following table:
Table 184. Instruction groups
Using a prebyte
The instructions are described with one to four opcodes.
In order to extend the number of available opcodes for an 8-bit CPU (256 opcodes), three
different prebyte opcodes are defined. These prebytes modify the meaning of the instruction
they precede.
The whole instruction becomes:
PC-2
PC-1
PC
PC+1
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
Condition code flag modification
