Instruction set
87/124
Using a prebyte
The instructions are described with 1 to 4 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:
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 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 90 Replace an X based instruction using immediate, direct, indexed, or inherent
addressing 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 indirect addressing mode.
It also changes an instruction using X indexed addressing mode to an
instruction using indirect X indexed addressing mode.
PIY 91
Replace an instruction using X indirect indexed addressing mode by a Y one.
11.2.1
Illegal opcode reset
In order to provide enhanced robustness to the device against unexpected behavior, a
system of illegal opcode detection is implemented. If a code to be executed does not
correspond to any opcode or prebyte value, a reset is generated. This, combined with the
Watchdog, allows the detection and recovery from an unexpected fault or interference.
Note:
A valid prebyte associated with a valid opcode forming an unauthorized combination does
not generate a reset.
