14.34.7 Instruction Set Summary
This section gives an overview of the
instruction set. This is intended as a
summary and definition of instruction
opcodes. Refer to section 14.34.8 for a
description of each instruction.
Each instruction consists of one byte
which is written to the RFST register to be
stored in the instruction memory.
The Immediate Strobe instructions (ISxxx)
are not used in a program. When these
instructions are written to the RFST
register, they are executed immediately. If
the CSP is already executing a program
the current instruction will be delayed until
the Immediate Strobe instruction has
completed.
For undefined opcodes, the behavior of
the CSP is defined as a No Operation
Strobe Command (SNOP).
