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:
Table 53.
Using a pre-byte
The instructions are described with one to four bytes.
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:
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:
Condition Code Flag modification
Conditional Bit Test and Branch
Unconditional Jump or Call
Interruption management
PC-2End of previous instruction
PC-1Prebyte
PCOpcode
PC+1Additional word (0 to 2) according to the number of bytes required to compute the
effective address
PDY 90Replace an X based instruction using immediate, direct, indexed, or inherent
addressing mode by a Y one.
PIX 92Replace an instruction using direct, direct bit, or direct relative addressing mode
to an instruction using the corresponding indirect addressing mode.
It also changes an instruction using X indexed addressing mode to an instruction using
indirect X indexed addressing mode.
PIY 91Replace an instruction using X indirect indexed addressing mode by a Y one.
