ABSTRACT:
A timer has a function of compensation calculation and includes a compensation value register 1 for holding a compensation value and an arithmetic unit 2 which adds or subtracts a compensation value ".alpha." held in the compensation value register 1 and a value "CC" of a count value C of a counter 3 at that time point, and by loading the operation result of the arithmetic unit 2 to the counter 3. Such a timer reduces a burden on a CPU and is capable of compensating the count value correctly regardless of a remaining time.
