Instruction Execution Time
Most instructions are single byte (with immediate ad-
dressing mode instructions requiring two bytes).
Most single byte instructions take one cycle time to ex-
ecute.
Skipped instructions require x number of cycles to be
skipped, where x equals the number of bytes in the
skipped instruction opcode.
The following tables shows the number of bytes and cycles
for each instruction in the format byte/cycle.
