Abstract
PURPOSE: To realize a timer function without adding a special hardware by adding +15 to the content of an RAM storing timer counted data to equivalently carry out a -1 counting operation.
CONSTITUTION: In an RAM30 there are memorized programs for accomplishing the timepiece operation and multifunctional operations other than the timepiece operation as a program memory part, and in an RAM31, there are memorized data memories such as time information or computing data, and further controlling memories. In an arithmetic logical operational circuit ALU33, time computation, numerical value operation or data comparison is carried out. To the content of the RAM storing the time computed content there is added +15 (1111 as binary data) whereby the -1 computing action which is the timer computing function is carried out equivalently, and the computation is carried out without adding any special hardware to the computing circuit to reduce the number of bits.
