*1 Column ST indicates conditions for changing status. Symbols have the following
meanings
S : On executing an instruction, status is unconditionally set.
C : Status is only set when carry or borrow has occurred in operation.
B : Status is only set when borrow has not occurred in operation.
E : Status is only set when equality is found in comparison.
N : Status is only set when equality is not found in comparison.
Z : Status is only set when the result is zero.
