– indicates that the flag is NOT AFFECTED by execution of the instruction
* indicates that the flag is SET OR CLEARED depending on execution of the instruction
** indicates that the flag is CLEARED by execution of the instruction
U indicates that the flag state is UNDEFINED following execution of the instruction; if the value of
this bit is needed for program execution, the program needs to check the bit prior to executing the
instruction with a U in a bit field.
