Abstract
A crank angle sensor generates a reference position signal and a crank angle signal as an internal combustion engine rotates. A counter counts the crank angle signals and, when its count value has reached a first set value, it goes to a second set value. Where the count value of the counter changed from the first to the second set value before the generation of the reference position signal, a control circuit sets the counter to the second set value when the reference position signal is generated. Where the count value of the counter did not change from the first to the second set value before the generation of the reference position signal, the control circuit sets the counter to the second set value when the counter is at the first set value and the reference position signal is produced.
