ABSTRACT:
A comparator is provided in the counter circuit to compare the counted value of clocks by a counter with the value of a register in which a target changing value of a comparison register which sets a value to be compared with the counted value of the counter is set. The value of the register is set in the comparison register when the counted value of the counter does not reach the set value of the register, whereas the value of the register is not set in the comparison register if the counted value does not reach the set value of the register, but the value of the comparison register is turned changeable at the desired timing while the counted value of the counter is being compared with the set value of the comparison register.
