11.11 PCP Instruction Set Details
This section describes the instruction set architecture of the PCP in detail.
11.11.1 Instruction Codes and Fields
All PCP instructions use a common set of fields to describe such things as the source
register, and the state of flags. Additionally, many instructions (including arithmetic and
many flow control instructions), are conditionally executed.
The descriptions of the PCP instructions are based on the following conventions.
>>, << Shift left or right, respectively.
[ ] Indirect access based on contents of brackets (de-reference).
#immNN Immediate value encoded into an instruction with width NN.
#offsetNN Address offset immediate value with width NN.
NextPC The current executing instruction’s address + 1.
(The next instruction to be fetched.)
cc_A, cc_B Condition Code CONDCA/CONDCB.
