INSTRUCTION SET OVERVIEW (Cont’d)
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 one to four op-
codes.
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:

fective address

be subdivided into 13 main groups as illustrated in
the following table:
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:
using immediate, direct, indexed, or inherent ad-
dressing mode by a Y one.
rect, direct bit, or direct relative addressing mode
to an instruction using the corresponding indirect
addressing mode.
It also changes an instruction using X indexed ad-
dressing mode to an instruction using indirect X in-
dexed addressing mode.
direct indexed addressing mode by a Y one.
