Instruction Behavior

The SET instruction behaves as follows:

  • The SET instruction turns ON the assigned BOOL data register, D, when the execution condition turns ON.
  • The SET instruction does NOT turn OFF the assigned BOOL data register, D, when the execution condition turns OFF.
    • To flip this behavior, refer to the RST instruction.
