RIEVTECH STUDIO SOFTWARE MANUAL This function has an attribute “ Date type ” . It can be “ 16-bit Unsigned ” or “ 32-bit unsigned number ” . In other words, only unsigned single word and unsigned double word can use this function. If the data type is “ 16-bit unsigned number ” , the value range is 0~65535. So the parameter of this function “ Digit bit ” can be 1~5. That means the number length is 1~5. “ 1 ” means units digit, “ 2 ” means tens digit, “ 3 ” means hundreds digit, “ 4 ” means thousands digit, and “ 5 ” means ten thousands digit. For example, if the “ Digit bit ” is 3 and the “ Mode ” is “ Add ” , it means the hundreds digit is operated for adding.
If the hundreds digit of a register is 6 and when this component is pressed down, the hundreds bit will change into 7, and then into 8 if it is pressed down again, and 9 again, 0 again, and 1 again, so the attribute of “ Add ” is similar to the “ Looping ” attribute. But, the “ Add ” or “ Subtract ” attribute of the “ Set up Figures by Bit ” function is only valid for one digit, and other digits are not changed. For example, if “ Digit bit ” is 3, “ Mode ” is “ Add ” , and the current register value is 18668, the value will change into 18768 when the component is pressed down, 18868 when it is pressed down again, 18968 again, 18068 again, 18168 again.
The maximum value of a single word is 65535. If the “ Digit bit ” is 5, the ten thousands digit will change in 0~5. l Logic Operation This function has four modes, “ And ” , “ Or ” , “ Exclusive-or ” and “ Not ” . The default mode is “ Add ” . 136
