The instruction set contains a wide variety of instructions. The available instructions are
listed below, organized into related groups.
Some instructions test a condition and skip the next instruction if the condition is not
true. Skipped instructions are executed as no-operation (NOP) instructions.
Arithmetic Instructions
The arithmetic instructions perform binary arithmetic such as addition and subtraction,
with or without the Carry bit.
Transfer-of-Control Instructions
The transfer-of-control instructions change the usual sequential program flow by
altering the contents of the Program Counter. The Jump to Subroutine instructions save
the Program Counter contents on the stack before jumping; the Return instructions pop
the top of the stack back into the Program Counter.
