7.2 INSTRUCTION GROUPS
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:
Using a pre-byte
The instructions are described with one to four
bytes.
In order to extend the number of available op-
codes for an 8-bit CPU (256opcodes), three differ-
ent prebyte opcodes are defined. These prebytes
modify the meaning of the instruction they pre-
cede.
The whole instruction becomes:
PC-2
End of previous instruction
PC-1
Prebyte
PC
opcode
PC+1
Additional word (0 to 2) according
to the number of bytes required to compute the ef-
fective address
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:
PDY 90
Replace an X based instruction
using immediate, direct, indexed, or inherent ad-
dressing mode by a Y one.
PIX 92
Replace an instruction using di-
rect, direct bit, or direct relative addressing mode
to an instruction using the corresponding indirect
addressing mode.
It also changes an instructionusing X indexed ad-
dressing modeto an instruction using indirect X in-
dexed addressing mode.
PIY 91
Replace an instruction using X in-
direct indexed addressing mode by a Y one.
