160. As shown in the timing diagram below, four keys connected with X35, X33, X31 and X30 are
pressed in order. Therefore, the number 5,301 is generated and stored in D0. 9,999 is the
maximum value allowed for D0. If the entered number exceeds the available range, the
highest digit performs overflow.
161. When X35 is pressed, M15 remains ON until another key is pressed and the rule applies to
other inputs.
162. M20 = ON when any of the keys is pressed.
163. When X20 is OFF, the value in D0 remains unchanged but M10~M20 will be OFF.
