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).
