Abstract
PURPOSE: To make it possible to greatly extend the processable time range and also easily read the unit which is displayed in the 4 digit numerical indicator, by containing a data representing the minimum unit into a time data of 4 digits.
CONSTITUTION: When a timer instruction code is detected by the routine 5, it is checked in the routine 6 whether or not 4 digits of a time data which has been inputted in RAM of the central processing unit 2 from the memory 5 are all "0". In case of an initial state, "DATA" is decided as NO, and it proceeds to the routine 7. The routine 7 checks whether or not a data of the lower third digit of the time data in RAM is "1101"=hexadecimal notation "D". When it has been decided as YES by the routine 7, it proceeds to the routine 8, and the lowest rank unit of the time data and the lower second digit unit are processed as 1min and 10min, respectively, the lower third digit is disregarded as a point data, and the highest rank digit unit is processed as 1hr. Time counting is performed at the time of "hour mode". When a data is decided as NO, it proceeds to the routine 9, and time counting of "second mode" and "minute mode" is performed.
