Instruction Table Key
•
Opcode
: A hexidecimal representation of the value that the mnemonic instruction represents.
•
Instruction
: The mnemonic syntax of the instruction.
•
Clocks
: The number of clock cycles it takes to complete this instruction. The numbers in parenthesis
are a breakdown of the total clocks. The number of clocks instructions take follows a general patern.
There are several Rabbit instructions that do not adhere to this pattern. Some instructions take more
clocks and some have been enhanced to take fewer clocks.
