20.0 Instruction Set
20.1 INTRODUCTION
This section defines the instruction set of the COP8 Family
members. It contains information about the instruction set
features, addressing modes and types.
20.2 INSTRUCTION FEATURES
The strength of the instruction set is based on the following
features:
• Mostly single-byte opcode instructions minimize program
• One instruction cycle for the majority of single-byte in-
• Many single-byte, multiple function instructions such as
• Three memory mapped pointers: two for register indirect
