5.3 ST7 INSTRUCTION SET
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 op-
codes.
In order to extend the number of available op-
codes for an 8-bit CPU (256 op-codes), three dif-
ferent prebyte opcodes are defined. These preb-
ytes modify the meaning of the instruction they
precede.
The whole instruction becomes:
PC-2
End of previous instruction
PC-1
Prebyte
PC
Op-code
PC+1
Additional word (0 to 2) according to the
number of bytes required to compute the
effective 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 90Replace an X based instruction using im-
mediate, direct, indexed, or inherent ad-
dressing mode by a Y one.
PIX 92 Replace an instruction using direct, direct
bit, or direct relative addressing mode to
an instruction using the corresponding in-
direct addressing mode.
It also changes an instruction using X in-
dexed addressing mode to an instruction
using
indirect
mode.
PIY 91 Replace an instruction using X indirect in-
dexed addressing mode by a Y one.
